50 Best Environmental Science Research Topics

May 31, 2023

research topics for phd in environmental science

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?

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!

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.

The NRESS Ph.D. in Natural Resources and Environmental Studies (NRES) focuses on problems dealing with the allocation and distribution of natural resources, policies at the local to global scale, and ethical and societal factors that affect resource management. Students typically enter the program with a bachelor's and/or master's degree in economics, environmental conservation, philosophy, political science, or sociology.

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.

Student Learning Outcomes

The Natural Resources and Environmental Studies (NRES) PhD degree within the Natural Resources and Earth Systems Science PhD Program trains scientists and scholars whose research addresses problems dealing with the allocation and distribution of natural resources, related policies at the local to global scale, and ethical and societal factors that affect resource management. Through interdisciplinary coursework and doctoral research, we train researchers who can independently pursue the process of science and scholarship, effectively apply their research to both solve basic questions in natural resource and environmental studies and apply their work to issues of relevance to society and the environment, especially in this era of global change. learning outcomes:

  • Critically review and cogently synthesize relevant literature, and identify need for new research.
  • Draw on previously published work to independently design and execute new experiments or field manipulations or develop models with a high degree of sophistication. The design and execution of an experiment or the building of a model should demonstrate an understanding of good laboratory, field or modeling practices.
  • Structure a coherent and convincing academic argument.
  • Lead the writing of manuscripts describing their research and its impacts that are suitable for publication in peer-reviewed journals or appropriate professional outlets for their particular sub-discipline, and be able to describe their research in presentations at national meetings of major relevant scientific societies, and at national and international symposia hosted by other professional organizations. The general expectation is that the final dissertation will include three first-authored publications submitted to or accepted in a peer-reviewed journal, or ready for submission.
  • Articulate how their research relates to a broader context outside of academia, and how their expertise will be applicable in the execution of complex research problems.

PhD in Environmental Health Sciences

The PhD program in Environmental Health Sciences (EHS) provides students with interdisciplinary training to better understand the impact of the environment on human health and disease. Students in the program have a wide range of unique opportunities for research and education through the participating departments across campus and the numerous health agencies affiliated with the program. Further, the program aims to produce a unique cadre of future leaders in the field of environmental health sciences who have expertise in both laboratory- and population-based research. Upon graduation, EHS students will have received comprehensive training in the EHS core areas of Exposure Science, Biological Mechanisms of Susceptibility and Disease, and Environmental Determinants of Population Health.

The EHS PhD program is offered through Emory University's James T. Laney School of  Graduate Studies.   If you are interested in learning more about Laney and the EHS program, we encourage you to complete this Inquiry Form . 

EHS Students - program header

What You'll Learn

Students participate in problem-based learning courses and take classes in areas like: research design and management, laboratory and field  methods in exposure science, environmental epidemiology, molecular toxicology,  public health ecology, risk assessment, and more.

What You'll Do

Students are required to complete three research rotations and have multiple  opportunities to collaborate with faculty and to explore interests within our three  major areas of research: Exposure science, biological mechanisms, and population  health.  

What You Need to Know

Students matriculate in the fall semester only.  This program is housed in the Gangarosa Department of Environmental Health at Rollins School of Public Health but administered through Laney Graduate School. Apply through the Laney Graduate School .

Application Process and Deadline

Applications for each fall cohort generally open a year in advance in September with a firm deadline of December 1. The EHS program only has a fall start date.

Apply through the Laney Graduate School  (not through SOPHAS) .

Training Areas

Exposure science.

This competency includes training in environmental chemistry,  environmental microbiology, environmental exposure assessment  and the use of exposure biomarkers.

Students learn the basic theory behind and practical methods for  sampling and analyzing chemical and microbiological  contaminants in environmental (air, water, soil, food, etc.) and  biological (exhaled air, blood, urine, etc.) factors. 

Gain training in:

  • Direct methods of assessment, including source and micro- environmental sampling and bio essays
  • Indirect methods like modeling and conducting survey  questionnaires
  • Analyzing and interpreting field samples in the lab
  • Communicating their results to a public health audience and apply t he techniques within a human health effects setting.

Biological Mechanisms of Susceptibility & Disease

Develop skills like:

  • A basic understanding of human physiology
  • Ability to identify factors affecting vulnerability to chemical exposures and  infectious agents
  • Ability to identify  pathophysiological consequences and  assessment (biomarkers) of such exposures

Though this area of study typically falls under the field of  toxicology, increased environmental exposures (including factors  like allergens, mold toxins, and infectious agents) make this  competency vital and relevant for global environmental health  students. This knowledge is important for understanding why  certain populations, such as children and the elderly, may exhibit  increased vulnerability to environmental hazards. 

Environmental Determinants of Population Health

This component focuses on how environmental exposures impact  human health on a population level, including proximal exposures  to environmental toxicants and infectious agents, and distal  environmental determinants like climate change, the built  environment, and environmental reservoirs of infectious disease.

Topics explored include:

  • Epidemiologic studies of environmental exposures
  • Risk assessment (which integrates data on external exposure,  internal dose, and disease)
  • Advanced and emerging risk assessment tools (like remote  sensing, geospatial and mathematical modeling, and air and water dispersion models)

Admission Requirements via Laney

  • Required prerequisite coursework includes college-level biology and chemistry. Statistics, calculus, organic chemistry, and physiology are also preferred, but not required. Accepted applicants who have not taken biology and chemistry may be asked to take these classes prior to matriculating in the fall.

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.

Environmental Science & Engineering

Environmental Science and Engineering at Harvard School of Engineering is an interdisciplinary program with the common goal of understanding, predicting and responding to human-induced environmental change.

Environmental scientists at Harvard address environmental issues such as global warming, stratospheric ozone depletion, and local and regional air and water pollution. This work requires perspectives from a diverse set of scientific disciplines including atmospheric physics and chemistry, oceanography, glaciology, hydrology, geophysics, ecology, and biogeochemistry. 

We view the earth's systems as a complex set of chemical, physical and biological interactions, made even more complicated by the various activities of human society. Through exploration of the underlying processes and feedbacks within the Earth system, and with a range of approaches from theory and modeling to experiments and observations, we train undergraduate and graduate students to think about environmental processes in an integrated fashion, preparing them to manage the environmental challenges we face.

Research is strongly interdisciplinary, with many connections to Earth and Planetary Sciences and other science and policy programs at Harvard.

National Institutes for Health boosts pay for PhD students and postdocs in the US

Rebecca Trager

  • No comments

The National Institutes for Health (NIH) has announced that it will substantially increase pay for the more than 17,000 early-career researchers supported by the agency’s National Research Service Awards (NRSAs), as well as increasing childcare subsidies.

The stipends for predoctoral scholars will rise by approximately 4% to $28,224 (£22,517), and those for postdoctoral scholars will jump by about 8%, with salaries starting at $61,008 and will rise based on experience. The agency aims to further increase pay over the next five years to reach the NIH Advisory Committee to the Director’s recommended starting stipend of $70,000 for postdoctoral NRSAs.

‘This is a significant step given a relatively flat NIH budget,’ explained Mike Lauer, the NIH’s deputy director for extramural research in a blog post . ‘The approach allows for an immediate stipend increase without drastic cuts to the number of available awards.’ He said this is the most substantial year-on-year increase for NRSA stipends since 2017. In addition, eligible recipients will also receive a $500 increase in childcare subsidies from $2500 to $3000 and another $200 for training-related expenses.

‘NIH is committed to improving the experience of postdoctoral scholars and helping them thrive in a competitive biomedical research environment,’ Lauer stated. ‘I believe implementation of these recommendations will go far in giving these scholars the sense of job security and career prospects that will lead to long careers in biomedical research.’

The reaction from the research community was upbeat. ‘This is where I see the pay increase as a big win. I’ve seen a lot of departments/unis use those stipend levels as caps for what students and postdocs can be paid,’ stated Joy Franco, a postdoc at Harvard Medical School in Boston, in a post on the social media platform X , formerly Twitter. ‘It will be a lot harder for them to justify setting a paycap that’s below NRSA levels,’ she added.

The American Society for Biochemistry and Molecular Biology (ASBMB) was also enthusiastic, applauding the NIH for supporting the next generation of scientists by increasing predoctoral and postdoctoral pay. ‘Policy changes like this are one vital part of ensuring a strong Stem workforce and thriving research enterprise,’ stated Sarina Neote, ASBMB’s director of public affairs. ‘However, to protect and strengthen America’s research leadership, both today and tomorrow, we must fully fund NIH, especially basic science research.’

Late last year, more than 5000 early-career researchers at the NIH voted by an overwhelming majority to form a union . They were primarily motivated to fight for improved pay and working conditions and enhanced protections against harassment and excessive workloads.
