Examples: Real Dissertation & Thesis Topics

While the ideas we’ve presented above are a decent starting point for finding a research topic, they are fairly generic and non-specific. So, it helps to look at actual dissertations and theses to see how this all comes together.

Below, we’ve included a selection of research projects from various environmental science-related degree programs to help refine your thinking. These are actual dissertations and theses, written as part of Master’s and PhD-level programs, so they can provide some useful insight as to what a research topic looks like in practice.

  • The physiology of microorganisms in enhanced biological phosphorous removal (Saunders, 2014)
  • The influence of the coastal front on heavy rainfall events along the east coast (Henson, 2019)
  • Forage production and diversification for climate-smart tropical and temperate silvopastures (Dibala, 2019)
  • Advancing spectral induced polarization for near surface geophysical characterization (Wang, 2021)
  • Assessment of Chromophoric Dissolved Organic Matter and Thamnocephalus platyurus as Tools to Monitor Cyanobacterial Bloom Development and Toxicity (Hipsher, 2019)
  • Evaluating the Removal of Microcystin Variants with Powdered Activated Carbon (Juang, 2020)
  • The effect of hydrological restoration on nutrient concentrations, macroinvertebrate communities, and amphibian populations in Lake Erie coastal wetlands (Berg, 2019)
  • Utilizing hydrologic soil grouping to estimate corn nitrogen rate recommendations (Bean, 2019)
  • Fungal Function in House Dust and Dust from the International Space Station (Bope, 2021)
  • Assessing Vulnerability and the Potential for Ecosystem-based Adaptation (EbA) in Sudan’s Blue Nile Basin (Mohamed, 2022)

  • Dry Season Water Quality Study on Three Recreational Sites in the San Gabriel Mountains (Vallejo, 2019)
  • Wastewater Treatment Plan for Unix Packaging Adjustment of the Potential Hydrogen (PH) Evaluation of Enzymatic Activity After the Addition of Cycle Disgestase Enzyme (Miessi, 2020)
  • Laying the Genetic Foundation for the Conservation of Longhorn Fairy Shrimp (Kyle, 2021).

Looking at these titles, you can probably pick up that the research topics here are quite specific and narrowly-focused , compared to the generic ones presented earlier. To create a top-notch research topic, you will need to be precise and target a specific context with specific variables of interest . In other words, you’ll need to identify a clear, well-justified research gap.

50 Best Environmental Science Research Topics

May 31, 2023

Environmental science is a varied discipline that encompasses a variety of subjects, including ecology, atmospheric science, and geology among others. Professionals within this field can pursue many occupations from lab technicians and agricultural engineers to park rangers and environmental lawyers. However, what unites these careers is their focus on how the natural world and the human world interact and impact the surrounding environment. There is also one other significant commonality among environmental science careers: virtually all of them either engage in or rely on research on environmental science topics to ensure their work is accurate and up to date.

In this post, we’ll outline some of the best environmental science research topics to help you explore disciplines within environmental science and kickstart your own research. If you are considering majoring in environmental science or perhaps just need help brainstorming for a research paper, this post will give you a broad sense of timely environmental science research topics.

What makes a research topic good?

Before we dive into specific environmental science research topics, let’s first cover the basics: what qualities make for a viable research topic. Research is the process of collecting information to make discoveries and reach new conclusions. We often think of research as something that occurs in academic or scientific settings. However, everyone engages in informal research in everyday life, from reading product reviews to investigating statistics for admitted students at prospective colleges . While we all conduct research in our day-to-day lives, formal academic research is necessary to advance discoveries and scholarly discourses. Therefore, in this setting, good research hinges on a topic in which there are unanswered questions or ongoing debates. In other words, meaningful research focuses on topics where you can say something new.

However, identifying an interesting research topic is only the first step in the research process. Research topics tend to be broad in scope. Strong research is dependent on developing a specific research question, meaning the query your project will seek to answer. While there are no comprehensive guidelines for research questions, most scholars agree that research questions should be:

1) Specific

Research questions need to clearly identify and define the focus of your research. Without sufficient detail, your research will likely be too broad or imprecise in focus to yield meaningful insights. For example, you might initially be interested in addressing this question: How should governments address the effects of climate change? While that is a worthwhile question to investigate, it’s not clear enough to facilitate meaningful research. What level of government is this question referring to? And what specific effects of global warming will this research focus on? You would need to revise this question to provide a clearer focus for your research. A revised version of this question might look like this: How can state government officials in Florida best mitigate the effects of sea-level rise?

 2) Narrow

Our interest in a given topic often starts quite broad. However, it is difficult to produce meaningful, thorough research on a broad topic. For that reason, it is important that research questions be narrow in scope, focusing on a specific issue or subtopic. For example, one of the more timely environmental science topics is renewable energy. A student who is just learning about this topic might wish to write a research paper on the following question: Which form of renewable energy is best? However, that would be a difficult question to answer in one paper given the various ways in which an energy source could be “best.” Instead, this student might narrow their focus, assessing renewable energy sources through a more specific lens: Which form of renewable energy is best for job creation?

 3) Complex

As we previously discussed, good research leads to new discoveries. These lines of inquiry typically require a complicated and open-ended research question. A question that can be answered with just a “yes” or “no” (or a quick Google search) is likely indicative of a topic in which additional research is unnecessary (i.e. there is no ongoing debate) or a topic that is not well defined. For example, the following question would likely be too simple for academic research: What is environmental justice? You can look up a definition of environmental justice online. You would need to ask a more complex question to sustain a meaningful research project. Instead, you might conduct research on the following query: Which environmental issue(s) disproportionately impact impoverished communities in the Pacific Northwest? This question is narrower and more specific, while also requiring more complex thought and analysis to answer.

4) Debatable

Again, strong research provides new answers and information, which means that they must be situated within topics or discourses where there is ongoing debate. If a research question can only lead to one natural conclusion, that may indicate that it has already been sufficiently addressed in prior research or that the question is leading. For example, Are invasive species bad? is not a very debatable question (the answer is in the term “invasive species”!). A paper that focused on this question would essentially define and provide examples of invasive species (i.e. information that is already well documented). Instead, a researcher might investigate the effects of a specific invasive species. For example: How have Burmese pythons impacted ecosystems in the Everglades, and what mitigation strategies are most effective to reduce Burmese python populations?

Therefore, research topics, including environmental science topics, are those about which there are ample questions yet to be definitively answered. Taking time to develop a thoughtful research question will provide the necessary focus and structure to facilitate meaningful research.

10 Great Environmental Science Research Topics (With Explanations!)

Now that we have a basic understanding of what qualities can make or break a research topic, we can return to our focus on environmental science topics. Although “great” research topics are somewhat subjective, we believe the following topics provide excellent foundations for research due to ongoing debates in these areas, as well as the urgency of the challenges they seek to address.

1) Climate Change Adaptation and Mitigation

Although climate change is now a well-known concept , there is still much to be learned about how humans can best mitigate and adapt to its effects. Mitigation involves reducing the severity of climate change. However, there are a variety of ways mitigation can occur, from switching to electric vehicles to enforcing carbon taxes on corporations that produce the highest carbon emission levels. Many of these environmental science topics intersect with issues of public policy and economics, making them very nuanced and versatile.

In comparison, climate change adaptation considers how humans can adjust to life in an evolving climate where issues such as food insecurity, floods, droughts, and other severe weather events are more frequent. Research on climate change adaptation is particularly fascinating due to the various levels at which it occurs, from federal down to local governments, to help communities anticipate and adjust to the effects of climate change.

Both climate change mitigation and adaptation represent excellent environmental science research topics as there is still much to be learned to address this issue and its varied effects.

2) Renewable Energy

Renewable energy is another fairly mainstream topic in which there is much to learn and research. Although scientists have identified many forms of sustainable energy, such as wind, solar, and hydroelectric power, questions remain about how to best implement these energy sources. How can politicians, world leaders, and communities advance renewable energy through public policy? What impact will renewable energy have on local and national economies? And how can we minimize the environmental impact of renewable energy technologies? While we have identified alternatives to fossil fuels, questions persist about the best way to utilize these technologies, making renewable energy one of the best environmental science topics to research.

3) Conservation

Conservation is a broad topic within environmental science, focusing on issues such as preserving environments and protecting endangered species. However, conservation efforts are more challenging than ever in the face of a growing world population and climate change. In fact, some scientists theorize that we are currently in the middle of a sixth mass extinction event. While these issues might seem dire, we need scientists to conduct research on conservation efforts for specific species, as well as entire ecosystems, to help combat these challenges and preserve the planet’s biodiversity.

4) Deforestation

The Save the Rainforest movement of the 1980s and 90s introduced many people to the issue of deforestation. Today, the problems associated with deforestation, such as reduced biodiversity and soil erosion, are fairly common knowledge. However, these challenges persist due, in part, to construction and agricultural development projects. While we know the effects of deforestation, it is more difficult to identify and implement feasible solutions. This is particularly true in developing countries where deforestation is often more prevalent due to political, environmental, and economic factors. Environmental science research can help reduce deforestation by identifying strategies to help countries sustainably manage their natural resources.

Environmental Science Topics (Continued)

5) urban ecology.

When we think of “the environment,” our brains often conjure up images of majestic mountain ranges and lush green forests. However, less “natural” environments also warrant study: this is where urban ecology comes in. Urban ecology is the study of how organisms interact with one another and their environment in urban settings. Through urban ecology, researchers can address topics such as how greenspaces in cities can reduce air pollution, or how local governments can adopt more effective waste management practices. As one of the newer environmental science topics, urban ecology represents an exciting research area that can help humans live more sustainably.

6) Environmental Justice

While environmental issues such as climate change impact people on a global scale, not all communities are affected equally. For example, wealthy nations tend to contribute more to greenhouse-gas emissions. However, less developed nations are disproportionately bearing the brunt of climate change . Studies within the field of environmental justice seek to understand how issues such as race, national origin, and income impact the degree to which people experience hardships from environmental issues. Researchers in this field not only document these inequities, but also identify ways in which environmental justice can be achieved. As a result, their work helps communities have access to clean, safe environments in which they can thrive.

7) Water Management

Water is, of course, necessary for life, which is why water management is so important within environmental science research topics. Water management research ensures that water resources are appropriately identified and maintained to meet demand. However, climate change has heightened the need for water management research, due to the occurrence of more severe droughts and wildfires. As a result, water management research is necessary to ensure water is clean and accessible.

8) Pollution and Bioremediation

Another impact of the increase in human population and development is heightened air, water, and soil pollution. Environmental scientists study pollutants to understand how they work and where they originate. Through their research, they can identify solutions to help address pollution, such as bioremediation, which is the use of microorganisms to consume and break down pollutants. Collectively, research on pollution and bioremediation helps us restore environments so they are sufficient for human, animal, and plant life.

9) Disease Ecology

While environmental science topics impact the health of humans, we don’t always think of this discipline as intersecting with medicine. But, believe it or not, they can sometimes overlap! Disease ecology examines how ecological processes and interactions impact disease evolution. For example, malaria is a disease that is highly dependent on ecological variables, such as temperature and precipitation. Both of these factors can help or hinder the breeding of mosquitoes and, therefore, the transmission of malaria. The risk of infectious diseases is likely to increase due to climate change , making disease ecology an important research topic.

10) Ecosystems Ecology

If nothing else, the aforementioned topics and their related debates showcase just how interconnected the world is. None of us live in a vacuum: our environment affects us just as we affect it. That makes ecosystems ecology, which examines how ecosystems operate and interact, an evergreen research topic within environmental science.

Environmental Research Topics: Features, Importance & Great Ideas

Environmental investigations entail investigating the natural world’s structure and function, the association between humans and the environment, and how people’s values, beliefs, and attitudes affect that association. Environmental research topics thus cover a wide range of subjects, including climate change, biodiversity, pollution, renewable energy, and sustainability.

How to Choose Environmental Topics for Research

Environmental investigations is a very broad field that offers a wide range of areas to investigate. So how can you choose a good one for your paper? First, always pick an issue from the area you are interested in. What is environmental science direction you’d like to develop? Working on your paper will be easier since you’ll be motivated to explore something you care about. From there, sort through your environmental topics for research to determine the following:

  • Relevance – does the proposal theme address an environmental issue with significant societal implications, such as pollution or climate change?
  • Originality –  does the investigation subject offer a new perspective on existing knowledge?
  • Feasibility – are the environmental topics to research realistic and achievable based on the scope and your available resources?
  • Scope – how broad is the matter of investigation? It shouldn’t be too broad or too narrow; it should be the right size to provide a comprehensive investigation.

When choosing environmental science research paper topics, avoid those that are too complex or require more resources and time than you can provide. Remember also to consider data availability, literature, funding, time, and ethical issues involved.

Environmental Topics for Research Paper Are Not Created Equal

Environmental science topics are created differently depending on your discipline, purpose, scope, and methodology. Thus, the approach used to formulate them differs as they will serve different purposes. For example, some are explanatory and will try to explain how something happens or works. Others will try to seek more knowledge about a subject(exploratory). Then, you might also encounter a few that compare and contrast two phenomena or situations.

When assessing investigation issues, carefully evaluate your goals and interests before committing to a specific one. Otherwise, you might get stuck. Luckily our research proposal writing services are always here to help you help to get out of even the most challenging situation!

Doctor of Philosophy in Environmental Health .

Program overview.

The PhD program in Environmental Health at Boston University School of Public Health provides students with specialized training and research experience in environmental epidemiology, exposure science, spatial epidemiology/GIS, climate and health, risk assessment, and toxicology, with an emphasis on environmental justice and community-engaged work. The program prepares graduates for careers in advanced research, teaching, policy, and leadership, and has been designed to ensure that students receive the training, research experience, resources, and support necessary to be successful. The average time to degree completion is 4.6 years. 

Our program is one of a small number of academic units nationally that specializes in investigating exposure-related health outcomes in community settings. Faculty are engaged with policy makers, community organizations, and vulnerable populations, working across numerous countries and domestically at the national, state, and local levels. Our dedicated faculty are committed to providing trainees with research opportunities that are consistent with a student’s research interests and that draw from our department’s experience conducting rigorous, innovative, and socially engaged research. We are also committed to providing inclusive educational experiences for students from a range of backgrounds, and are committed to diversity, equity, and inclusion both within our department and across the field of environmental health. Please see the website for our Diversity, Equity, and Inclusion Committee for more information on our ongoing activities. 

The Department of Environmental Health engages in a wide range of collaborative research. Major areas of interest include the health effects of air pollution and a changing climate, such as through the Center for Climate and Health  at BUSPH; complex mixtures of chemicals, such as chemicals contained in consumer products as well as contaminants of water, food, and soil; non-chemical hazards such as noise, heat, and social stressors; and combinations of chemical and non-chemical exposures that accumulate or interact to harm health. Vulnerable populations such as children, military veterans, and people living in poverty in the U.S. and internationally are of special interest to us.

Students are engaged in research projects with faculty throughout the program. To gain research experience and identify a dissertation topic, students complete research rotations with faculty. All PhD students also serve as teaching assistants at least once during their time in the program and are involved with departmental activities such as seminar planning, journal clubs, and an annual department retreat.

Program Elements

Our PhD students engage in full-time coursework for the first one to two years of the program, a minimum of 32 credits (with prior relevant master’s degree) or 64 credits (without prior relevant master’s degree), depending on level of preparation prior to admission. 

The EH PhD program requires coursework in environmental health, epidemiology and biostatistics. Coursework is organized as six required courses, additional courses in three different training areas, and electives.

Research Rotations

Our research rotation program allows students to become involved in research during their first year and is designed to assist students in the process of identifying a dissertation topic. Specifically, students participate in a research rotation during each of their first three semesters (fall, spring, summer). Students work with their advisor to select research rotations based on their interests, which provides opportunities to work with different faculty members and gain experience on different projects.

Teaching Opportunities

Our program is committed to providing doctoral students with opportunities to develop their teaching skills. Each year, our department offers teaching assistant opportunities associated with several different classes. Students are required to serve as a teaching assistant in at least one class during their time in the program, though most choose to do so more than once.

Seminar, Proseminar, Journal Club, Department Retreat

Our PhD students participate in a doctoral seminar (every week), a doctoral proseminar (monthly), a journal club (monthly) and an annual research retreat, all of which represent key elements of our program.

  • The  Gijs van Seventer Environmental Health Seminar  provides trainees the opportunity to engage in an academic seminar addressing substantive topics in environmental health. 
  • The Doctoral Proseminar (short for professional seminar) covers topics not typically addressed in traditional coursework but critical to professional development (e.g., grant writing, strategies for preparing a manuscript, strategies for managing data, etc.).
  • The Journal Club allows students to gain experience reviewing and critiquing scientific journal articles, stay abreast of the literature in the field, and become more familiar with diverse topics across the field of environmental health.
  • The annual EH Department Retreat is held each fall at an off-site location over 1-1½ days. The primary goals of the research retreat are to: enhance the cohesiveness of faculty and students while sharing ideas and developing new opportunities; provide trainees with an additional opportunity to discuss their research; allow trainees to hear about ongoing research projects both within and outside the department; and create an event that facilitates the social and professional transition of new trainees and new faculty members in the program. 

Qualifying Exam

After completing coursework, each trainee submits an application to the Doctoral Committee for approval to take qualifying exams. The application consists of a dissertation proposal in the form of a federal grant proposal and a copy of their unofficial transcript. The qualifying exam includes a written and an oral component.

Dissertation

Each student works closely with their advisor and dissertation committee while conducting their research and preparing their dissertation. The dissertation takes the form of 3 publishable papers, plus an abstract, introduction, and conclusion. Ultimately, students present their dissertation in a public forum that all individuals are welcome to attend.

We ensure that each of our admitted PhD students has all of the following:

  • Full financial support, including stipend, tuition and fees, health insurance, a computer, and support for travel to scientific conferences;
  • A faculty mentor with the experience and expertise necessary to train the student in their area of interest; and
  • Research opportunities that are consistent with the student’s research interests that can serve as the basis for their dissertation.

A T32 training grant from the National Institute of Environmental Health Sciences (PI: Claus Henn), in combination with traineeships through the BU Graduate Program in Urban Biogeoscience and Environmental Health (PIs: Levy, Templer, Hutyra), individual training awards, and individual research grants, provide the resources necessary to ensure that our PhD students receive full financial support for the duration of their program.

About the PhD in Environmental Health Program

The Doctor of Philosophy (PhD) degree program is a full-time degree program that offers a unique interdisciplinary learning experience where the course of study is individually tailored based on the student’s interest in understanding and finding solutions to pressing problems in environmental health and engineering.

The goal of PhD training in EHE is to prepare graduates to engage in scholarship and professional practice that creates new knowledge, use research to transform practice and improve the health of the environment and the public, and effectively communicate research findings to the public. The program requires didactic coursework followed by an average of four to five years of research towards a doctoral dissertation (also referred to as a thesis on official forms and committees).

Training is offered through a core curriculum that is required of all PhD students in the Department with the addition of track/program-specific requirements and focused courses in specialized areas.

Students are expected to tailor their curricula, working with their advisers to create a comprehensive plan of study and research. PhD thesis must be based on original research, worthy of publication, and approved by the Department and a committee of thesis (dissertation) readers. PhD students must also be engaged in primary data collection as a component of their dissertation research or embedded in other research during their training here.

Our programs are offered in the  Whiting School of Engineering , on the Homewood campus (WSE) and the  Bloomberg School of Public Health  (BSPH) East Baltimore campus. Students in all of our programs have the unique opportunity to take classes on both the Homewood and East Baltimore campuses in order to complete their degree requirements.

Curriculum & Requirements

Program description.

The graduate program in Natural Resources and Earth Systems Science (NRESS) is an interdepartmental program offering the Ph.D. degree for interdisciplinary work in areas related to the understanding and management of the environment in the broadest context. Areas of study include, but are not limited to, ecosystem science, biogeochemical cycling, geochemical systems, atmospheric science, environmental philosophy, forestry, geologic science, hydrology, marine science, oceanography, social science, environmental policy and ethics, environmental education, and multidisciplinary natural resources management.

Earth and Environmental Sciences (EES)

The NRESS Ph.D. in Earth and Environmental Sciences (EES) focuses on problems dealing with the physical, chemical, and/or biological processes that affect earth and environmental systems. Students receiving the Ph.D. degree in EES will typically have a bachelor's and/or master’s degree in biology, ecology, environmental science, geology, hydrology, or microbiology.

Requirements for the Program

Degree requirements.

The requirements of the doctoral program are flexible to accommodate the diverse interests and needs of students. All students in the NRESS program must meet the requirements listed below.

Committees and Coursework

The Ph.D. guidance and dissertation committees must consist of at least five members. The chair must be a member of the NRESS faculty . Three of the five members (including the chair) must be NRESS faculty, and committee members must be from more than one academic department. Students are strongly encouraged to include at least one off-campus member. Off-campus committee members must hold a doctoral (or terminal) degree and be approved by the student's adviser, the NRESS Program, and the Graduate School dean. Students should select the guidance committee in a timely manner, within one year for full-time students and two years for part-time students.

Core Area Course Requirements

All students will take one course in each of four core areas while enrolled in the program: natural sciences, ethics/policy/law, methods, and seminar. Students are also required to take NRES 997 Interdisciplinary Research in Natural Resources and Earth and Environmental Sciences , preferably within the first year of enrollment. Any course used to satisfy the natural sciences, ethics/policy/law, and methods core areas must be a classroom course of at least 3 credits. The seminar course must be interactive and must be at least 1 credit. Independent study courses may not be used to satisfy core requirements. Students must complete a Preliminary Coursework Approval Form, which lists the student's planned coursework, within one year for full-time students and two years for part-time students. A Final Course Approval Form, with signatures from the adviser, committee members, and the NRESS program chair is submitted once the coursework is completed.

Students Entering the Program without a Master's Degree

Students entering the program without a master's degree are expected to complete a minimum of 36 credit hours. There is not a specific credit requirement beyond the required four core courses and NRES 997 for students who have completed a M.S. or M.A. degree in a related field. Students enter the NRESS program with diverse backgrounds and preparation in their desired area of study. Therefore, final credit requirements are determined by the guidance committee and may include additional coursework necessary to enhance the student's selected field of study and/or correct any deficiencies in the student's previous program. Students may apply a maximum of 12 credits of independent study and/or seminar courses to their total course requirement.

Transfer Credits

Graduate-level courses taken prior to admission may be transferred into the program and applied to the total only if they were not taken while matriculated in another degree program, as per Graduate School policy. These courses may not be used to meet the core course requirements. Transfer of credits must be approved by the adviser, the guidance committee, and the Graduate School.

Language Proficiency

Language proficiency may be required at the discretion of the student's adviser/committee. If required, a student will need to show proficiency in one foreign language or one computer language.

Examinations

Each student is required to pass three examinations, each of which has both a written and oral component. Additional preliminary examinations may be administered before the three required exams as the committee deems necessary. Performance on such an exam will determine areas where the student needs additional coursework or could result in the student's removal from the program.

Comprehensive exam (sometimes referred to as the qualifying exam) : The student must prepare an extensive written answer to one question from each committee member that covers the basic concepts and factual material deemed essential for the student’s program. Three weeks are allowed for completion of the exam during which time students are expected to work solely on their answers.  Answers are expected to be anywhere from 10 – 20 pages per question with extensive literature citations. Completed written answers are submitted to the adviser who then distributes copies to the other committee members for review.  Approximately 1 – 2 weeks are allowed for the committee to read the answers, after which time the student gives an oral presentation to the committee. Following the presentation, committee members will ask for clarification of the student’s answers, if necessary.  The committee may require a student to repeat part, or all, of the comprehensive exam if the student’s performance is deemed unsatisfactory. This exam should be taken within three years of initiation of graduate study in the program.

Proposal exam: The student must present to the committee a written proposal on the dissertation research topic. Once the proposal is written, the student will complete a public oral presentation of the proposed research, followed by an oral examination by the committee.

Final exam: The student must complete a written Ph.D. dissertation prior to the final exam. Once written, the student is required to complete an oral defense of the dissertation, which will include both a public presentation and oral examination by the committee.

A student may be required to take additional courses following either the comprehensive or proposal exam, or may be removed from the program following failure of any of the required exams. Students are advanced to candidacy after successfully completing the comprehensive exam, proposal exam, and all coursework required by the guidance committee as summarized on the Coursework Approval Form.

A bright and airy hub for climate at MIT

Press contact :.

Exterior of the two-story glass Building 55 atrium extends from the concrete 21-story Building 54 tower, reflecting the sky and trees.

Previous image Next image

Seen from a distance, MIT’s Cecil and Ida Green Building (Building 54) — designed by renowned architect and MIT alumnus I.M. Pei ’40 — is one of the most iconic buildings on the Cambridge, Massachusetts, skyline. Home to the MIT Department of Earth, Atmospheric and Planetary Sciences (EAPS), the 21-story concrete structure soars over campus, topped with its distinctive spherical radar dome. Close up, however, it was a different story.

A sunless, two-story, open-air plaza beneath the tower previously served as a nondescript gateway to the department’s offices, labs, and classrooms above. “It was cold and windy — probably the windiest place on campus,” EAPS department head Robert van der Hilst, the Schlumberger Professor of Earth and Planetary Sciences, told a packed auditorium inside the building in March. “You would pass through the elevators and disappear into the corridors, never to be seen again until the end of the day.”

Van der Hilst was speaking at a dedication event to celebrate the opening of the renovated and expanded space, 60 years after the Green Building’s original dedication in 1964. In a dramatic transformation, the perpetually-shaded expanse beneath the tower has been filled with an airy, glassed-in structure that is as inviting as the previous space was forbidding.

Designed to meet LEED-platinum certification, the newly-constructed Tina and Hamid Moghadam Building (Building 55) seems to float next to the Brutalist tower, its glass façade both opening up the interior and reflecting the sunlight and green space outside. The 300-seat auditorium within the original tower has been similarly transformed, bringing light and space to the newly dubbed Dixie Lee Bryant (1891) Lecture Hall, named after the first person to earn a geology degree at MIT.

Catalyzing collaboration

The project is about more than updating an overlooked space. “The building we’re here to celebrate today does something else,” MIT President Sally Kornbluth said at the dedication.

“In its lightness, in its transparency, it calls attention not to itself, but to the people gathered inside it. In its warmth, its openness, it makes room for culture and community. And it welcomes in those who don’t yet belong … as we take on the immense challenges of climate together,” she continued, referencing the recent launch of The Climate Project at MIT — a whole-of-MIT initiative to innovate bold solutions to climate change. In MIT’s famously decentralized structure, the Moghadam Building provides a new physical hub for students, scientists, and engineers interested in climate and the environment to congregate and share ideas.

From the start, fostering this kind of multidisciplinary collaboration was part of Van der Hilst’s vision. In addition to serving as the flagship location for EAPS, Building 54 has long been the administrative home of the MIT-WHOI Joint Program in Oceanography/Applied Ocean Science and Engineering — a graduate program in partnership with Woods Hole Oceanographic Institute. With the addition of Building 55, EAPS has now been joined by the MIT Environmental Solutions Initiative (ESI) — a campus-wide program fostering education, outreach, and innovation in earth system science, urban infrastructure, and sustainability — and will welcome closer collaboration with Terrascope — a first-year learning community which invites its students to take on real-world environmental challenges.

A shared vision comes to life

The building project dovetailed with the long-overdue refurbishment of the Green Building. After a multi-year fundraising campaign where Van der Hilst spearheaded the department’s efforts, the project received a major boost from lead donors Tina and Hamid Moghadam ’77, SM ’78, allowing the department to break ground in November 2021.

In Moghadam, chair and CEO of Prologis, which owns 1.2 billion square feet of warehouses and other logistics infrastructure worldwide, EAPS found a fellow champion for climate and environmental innovation. By putting solar panels on the roofs of Prologis buildings, the company is now the  second largest on-site producer of solar energy in the United States. “I don’t think there needs to be a trade-off between good sound economics and return on investment and solving climate change problems,” Moghadam said at the dedication. “The solutions that really work are the ones that actually make sense in a market economy.”

Architectural firm AW-ARCH designed the Moghadam Building with a light touch, emphasizing spaciousness in contrast to the heavy concrete buildings that surround it. “The kind of delicacy and fragility of the thing is in some ways a depiction of what happens here,” said architect and co-founding partner Alex Anmahian at the dedication reception, giving a nod to the study of the delicate balance of the earth system itself. The sense is further illustrated by the responsiveness of the façade to the surrounding environment, which, depending on the time of day and quality of light, makes the glass alternately reflective and transparent.

Inside, the 11,900-square foot pavilion is highly flexible and serves as a showcase for the science that happens in the labs and offices above. Central to the space is a 16-foot by 9-foot video wall featuring vivid footage of field work, lab research, data visualizations, and natural phenomena — visible even to passers-by outside. The video wall is counterposed to an unpretentious set of stair-step bleachers leading to the second floor that could play host to anything from a scientific lecture to a community pizza-and-movie night.

Van der Hilst has referred to his vision for the atrium as a “campus living room,” and the furniture throughout is intentionally chosen to allow for impromptu rearrangements, providing a valuable public space on campus for students to work and socialize.

The second level is similarly adaptable, featuring three classrooms with state-of-the-art teaching technologies that can be transformed from a single large space for a hackathon to intimate rooms for discussion.

“The space is really meant for a yet unforeseen experience,” Anmahian says. “The reason it is so open is to allow for any possibility.”

The inviting, dynamic design of the pavilion has also become an instant point of pride for the building’s inhabitants. At the dedication, School of Science dean Nergis Mavalvala quipped that anyone walking into the space “gains two inches in height.”

Van der Hilst quoted a colleague with a similar observation: “Now, when I come into this space, I feel respected by it.”

The perfect complement

Another significant feature of the project is the List Visual Arts Center  Percent-for-Art Program installation by conceptual artist Julian Charrière, entitled “Everything Was Forever Until It Was No More.”

Consisting of three interrelated works, the commission includes:  “Not All Who Wander Are Lost ,” three glacial erratic boulders which sit atop their own core samples in the surrounding green space; “ We Are All Astronauts ,” a trio of glass pillars containing vintage globes with distinctions between nations, land, and sea removed; and “ Pure Waste ,” a synthetic diamond embedded in the foundation, created from carbon captured from the air and the breath of researchers who work in the building.

Known for themes that explore the transformation of the natural world over time and humanity’s complex relationship with our environment, Charrière was a perfect fit to complement the new Building 55 — offering a thought-provoking perspective on our current environmental challenges while underscoring the value of the research that happens within its walls.

GLOBE Alumna and Youth for Habitat Program Lead Named Scientist of the Month in Alaska

As a 16-year old high school graduate, Maggie House decided to leave the military base in Germany where she lived with her family and go to college close to nature in Fairbanks, Alaska. She had lived in many countries and US states and knew she was ready. At the University of Alaska Fairbanks Troth Yeddha’ campus in Fall 2022, Maggie enrolled in a 300-level Watershed Management course, which required all students to implement a Global Learning and Observations to Benefit the Environment (GLOBE) project and poster. Maggie’s project focused on using the GLOBE Observer App to monitor the erosion of nearby Cripple Creek, which had a history of mining and made Fairbanks famous for its gold. She and a classmate wrote a funded mini-grant proposal to study how ice was related to erosion. While not on the frozen creek, Maggie worked as a student employee with the NASA Science Activation Program's Arctic and Earth STEM Integrating GLOBE and NASA (SIGNs) team at the International Arctic Research Center, during which she trained teachers and mentored students at Alaska’s first-ever Student Research Symposium in 2022. Maggie also wrote an article about the symposium, published on the University of Alaska Fairbanks News page: https://www.uaf.edu/news/alaskan-youth-present-research-earth-day-symposium.php

When the ice melted and the symposium ended, Maggie wanted to study the freshwater habitats of the Creek using GLOBE hydrosphere protocols, so she wrote another proposal. Maggie got a full scholarship and grant funding through Biomedical Learning and Student Training (BLaST), supported by the National Institutes of Health. Her work earned recognition in the US Fish and Wildlife Service story, “Natural Flows Return to Cripple Creek” and honors as the December 2023/January 2024 BLaST Scientist of the Month . The story does not stop there. In May, 2024, Maggie House graduated with a Bachelor of Science degree and received the first-ever GLOBE internship at the Fairbanks Soil and Water Conservation District, where Maggie House leads the summer Youth for Habitat program for middle school students. Today, you can find Maggie in Cripple Creek near Fairbanks, Alaska, teaching students to learn science by doing science.

“I have a firm belief that the health of our environment is intertwined with the health of humans. I am interested in making science-related issues more understandable, for everyone to be a part of their local community. In my future, I see myself continuing to work towards strengthening the relationship between humans and nature and promoting the conservation of our dependence on one another.” - Maggie House

Arctic and Earth SIGNs created the conditions for Maggie as an undergraduate student to collect OpenSource GLOBE data that contributed to local solutions, to be awarded funding to pursue actionable research, and to be a leader for educators and future learners. Maggie's data on ice conditions informed the engineering redesign of the Cripple Creek stream restoration project. Her success in using GLOBE protocols and culturally responsive research methods modeled by Arctic and Earth SIGNs gave her the confidence to write a research proposal and be awarded a full undergraduate research scholarship. Maggie was the first person in the world to monitor aquatic invertebrates in Cripple Creek just three weeks after flow was restored to the creek after 85 years. In Arctic and Earth SIGNs, environmental stewardship is a culminating part of the Learning Framework. Now, Maggie leads the stewardship of salmon habitat in Cripple Creek and mentors middle school youth to pursue STEM fields as a GLOBE trainer and mentor. Maggie's story matters because one person, with a Science Activation support network and a focus on real-world environmental issues, can make a difference.

Arctic & Earth SIGNs is supported by NASA under cooperative agreement award number NNX16AC52A and is part of NASA’s Science Activation Portfolio.

The image is divided horizontally by an undulating line between a cloudscape forming a nebula along the bottom portion and a comparatively clear upper portion. Speckled across both portions is a starfield, showing innumerable stars of many sizes. The smallest of these are small, distant, and faint points of light. The largest of these appear larger, closer, brighter, and more fully resolved with 8-point diffraction spikes. The upper portion of the image is blueish, and has wispy translucent cloud-like streaks rising from the nebula below. The orangish cloudy formation in the bottom half varies in density and ranges from translucent to opaque. The stars vary in color, the majority of which have a blue or orange hue. The cloud-like structure of the nebula contains ridges, peaks, and valleys – an appearance very similar to a mountain range. Three long diffraction spikes from the top right edge of the image suggest the presence of a large star just out of view.

Amos M. Nur, the Wayne Loel Professor of Earth Sciences, Emeritus, at Stanford University and broadly acknowledged as one of the world’s foremost experts in geology and geophysics, died of a heart attack at his home on the Stanford campus on June 10, 2024. He was 86.

Nur founded and was a longtime director of the Stanford Rock Physics and Borehole Geophysics Project. He excelled in seismic monitoring and computational digital geophysics. He used this knowledge to understand and predict earthquakes and to explore rock formations for petroleum and geothermal steam. He also pioneered the science of “seismic velocity measurements” to monitor the evolving states of oil and gas reserves as fluid was pumped out.

“It’s very difficult in my opinion to envision the process from reading about it,” Nur once said. “But by using movies in Earth sciences, we would not only be far more educational, but it would give us insight into geological processes.”

“Amos was an ‘ideas’ person. He loved coming up with new ideas and he inspired those around him to do the same. Every time I shared an idea with him, his eyes – actually, all of him – lit up and he would nod encouragingly, waiting to hear more,” remembered Professor Rosemary Knight, whom Nur advised during her doctoral work at Stanford in the early 1980s and who later joined him on the faculty. “I have never forgotten his way of letting me know that ideas matter – that my ideas matter. It was working with Amos that inspired me to choose life as a faculty member, and to foster in my own research group an environment that encourages and celebrates student creativity and self-confidence.”

“Volcano” of ideas

Nur described his full-circle evolution – from an early interest studying rocks in general to exploring the broader laws of geophysics and back again – to fundamental geology. “There were two facets about geology that, at the time, began to make me feel uneasy. It felt inconclusive and I wasn’t able to prove anything. I heard the term ‘geophysics’ and it sounded right. It was only much later that I began to appreciate geology. Geophysics is a tool that helps us to find partial answers about the Earth, but the big questions really come from geology,” Nur explained.

“Amos had an uncanny ability to work at the intersection of disciplines. I arrived at Stanford in 1982 as Professor of Petroleum Engineering. We were soon discussing integrating my fluid flow modeling with his geophysical monitoring to advance predictions about the behavior of petroleum reservoirs,” said friend and colleague Khalid Aziz, Otto N. Miller Professor, Emeritus. “Amos was instrumental in the creation of what is now the Stanford Center for Earth Resources Forecasting (SCERF), attracting new colleagues and funding sources. SCERF would not have been possible without him.”

He would later apply his myriad skills to study the relationship between earthquakes and archaeology. He published over 250 peer-reviewed papers and authored three books. His best known tome was 2008’s Apocalypse: Earthquakes, Archaeology, and the Wrath of God , which posited that biblical accounts, mythology, and the archaeological record held clues that ancient civilizations were destroyed by earthquakes, not by wars.

“You need only look at Amos’ CV and the way it changed over time to realize that this was a person constantly on the lookout for the next fascinating topic to work on,” Knight said.

“When I retired, I discovered that I had so many projects or ideas that I thought I would start. And I realized how many of them I’m not going to do because there’s not much time left,” he would say of his new interests in retirement.

In addition to his fundamental research, Nur was also an influential teacher revered by his students. Nur proudly listed by name the many advisees he had mentored to their graduate degrees and their current places of employment in academia, government, and industry throughout the world. From 2000-2005, Nur was also director of the Bing Overseas Studies Program that provides transformational educational experiences in stimulating settings throughout the world.

“Amos was a volcano of ideas,” said his widow, Francina Lozada-Nur, a professor emerita at the University of California, San Francisco. “He was extremely creative. I think he passed that on to his students. He was very inspirational.”

Oft-honored academic

Amos Michael Nur was born February 9, 1938, in Haifa, in what is now Israel. He was raised on a farm, which he credited with piquing his early interest in geology. Nur earned his Bachelor of Science in geology at Hebrew University, Israel, in 1962. His PhD in geophysics at MIT came in 1969. He joined the Stanford faculty a year later, serving until his retirement in 2008.

He was chair of the Stanford Geophysics Department twice, from 1986 to 1991 and from 1997 to 2000. In 1974, Nur earned the American Geophysical Union’s Macelwane Medal, recognizing significant early career contributions to Earth and space science. In 2011, he won the Ewing Medal from the Society of Exploration Geophysics. Nur was also an elected member of the National Academy of Engineering and a fellow of the American Geophysical Union, the Geological Society of America, and the California Academy of Sciences.

Nur was conferred an honorary doctorate at his hometown’s University of Haifa in 2013. In its dedication, the school singled out Nur for “his groundbreaking research in Earth sciences, his academic excellence and constant determination to shape new knowledge that advances humanity to reach new frontiers.”

Nur is survived by his wife, Dr. Francina Lozada-Nur of Stanford, California; son, Boaz Nur of Barcelona, Spain; and three grandchildren, Sofia, Sebastian, and Olivia Nur, all of Barcelona.

There will be a celebration of the life of Amos Nur on February 9, 2025, at 10:30 a.m. on the Stanford campus. Details will be available on the Geophysics Department website. The family requests gifts in memory of Amos Nur be made to the Stanford Department of Music or Stanford Live General Gifts.
