Research Depth

Our students and faculty pursue interdisciplinary research across diverse areas. Review our recent Research, including peer-reviewed articles by students as first authors.

DC Career Launch

DC offers the nation's highest median salary for environmental scientists at $123,000 and double the national job concentration. Entry level salaries average in the $60,000s.

Stopping Food Waste

AU faculty, working with 13 institutions, launched the first national academic research network on wasted food.

Specialize Your Studies

3 students doing seaside fieldworkThe program offers students the option to pursue either scientific/research or policy/advocacy tracks, both open to interdisciplinary specialization:

  • Thesis option for those interested primarily in scientific research careers: Students work with a faculty mentor to define a research project during their first year of study.
  • Non-thesis option for those pursuing careers in environmental policy or advocacy: Faculty assist students in securing an internship and complementary elective coursework by the end of their first year.

Ongoing areas of faculty and student specialization include the following non-exhaustive list, continually expanding, and beyond which students may pursue their own niche subfields:

  • Atmospheric aerosol from volcanic eruptions, forest fires, and man-made pollution 
  • Contaminants and geochemistry of freshwater systems and agricultural watersheds
  • Food systems, food waste, seafood globalization, and related system- and data-modeling
  • Nutrient pollution and climate change affects on coral reefs
  • Urban tree cooling and heating, boreal forests, carbon monitoring, and related software
  • Watershed urbanization and green infrastructure

While completing their studies, our students often publish as first and second authors on a wide range of topics, from urban forest macroinvertebrates to effects of oil and gas on regional water quality, or intern with local and international organizations, including the US Congress, EPA, and NSF, the Environmental Defense Fund, and Center for International Environmental Law.

Spotlight: Hannah Nisonson

Hannah Niconson.I have always had a passion to improve the world around me. AU was the perfect gateway to helping me understand where science and true societal progress intersect. My professors were dedicated to my success and taught me the practical tools to achieve a career in environmentalism. Not only was I able to learn hard skills like R and GIS, but I was also able to leverage that with the realistic applications of these tools. This landed me a position as a marine spatial scientist with NOAA after graduation. It has been a perfect balance.
Hannah Nisonson, MS '22

Hannah Nisonson’s passion for environmental justice has led her to pursue an MS in environmental science at American University and a prestigious fellowship at DC’s Global Environment and Technology Foundation, where she is building research databases for blue carbon sequestration methods. Her goal is to find alternative ways to reduce blue carbon in and around the ocean, potentially by carbon sequestration and oceanic carbon credits.

Hannah says she hopes environmental justice will always be at the forefront of her life. At AU, she is a merit scholarship recipient and teaches an environmental science lab to undergraduate students. “I love a space where I can share my passion and knowledge for environmental science,” she says.

Hannah is also looking forward to working with Associate Professor of Environmental Science Sauleh Siddiqui, the principal investigator on a National Science Foundation-funded food waste grant—the largest-ever grant in AU history. She hopes to help with the data analysis and visualization for the project.

It’s a perfect fit for Hannah, who came from a technical undergraduate engineering background and plans on pursuing a doctorate in environmental science and a career as a professor at a scientific research institution.

Career Outlook

The Bureau of Labor Statistics reports a median annual salary over $76,000 for Environmental Scientists nationwide (as of 2021) with steady annual job growth of 5 percent nationally. Washington, DC, offers the nation's highest median salary, $123,000, and nearly double the national job concentration.

In DC and surrounding areas, you'll be able to take advantage of the concentration of federal and state agencies, private consultancies, business, NGOs — and AU's active alumni network and environmental science grads — to find career choices you want. Recent graduates have gone on to a range of positions such as

  • Biophysical Society: Programs Coordinator
  • Florida Fish & Wildlife Conservation Commission: Biological Scientist
  • Integrated Systems Solutions: Management Analyst III
  • Kapur & Associates: Environmental Scientist
  • Las Vegas Water District: Analytical Chemist
  • McDonoungh Braungart Design Chemistry: Environmental Scientist
  • National Science Foundation: Program Analyst
  • NOAA: Fishery Observer 
  • NOAA: GIS Technician
  • Solv LLC: Environmental Scientist
  • US EPA: Data Analyst
  • Washington DC Dept. of Transportation: Urban Forester
  • Wildlife Habitat Council: Conservation Planning Manager
  • World Bank: International Affairs Consultant

What You'll Walk Away With

  • Grounding in environmental systems and science: ability to understand and evaluate interdisciplinary approaches encompassing natural, physical, and social sciences.
  • Analytical problem-solving: ability to choose and apply empirical methods, tools, and professional judgment in evaluating quantitative, qualitative, spatial (GIS) data.
  • Integrative learning: ability to blend disparate components of natural, social, and technological systems and resources.
  • Teamwork and leadership skills: practical experience gained in fieldwork, shared research projects, or internships.
  • Community and practical engagement: real-world experience engaging scholarly, organizational, and local publics in ways responsive to their tacit and overt needs. 
  • DC connections and the reach of American University’s network.

FAQ

Most graduate students receive financial support. There are merit-based tuition awards and stipends for being a teaching assistant. In a typical academic year, around 64% of our students receive some level of AU funding through research or teaching. Of those not supported by AU, 25% were funded by other sources.

Yes, but it is more difficult to get financial support, which is generally given to full-time students. Six credits per semester is considered full time for financial purposes, though most full-time students take nine credits per semester.

The thesis track gives students experience doing their own complex study and learning the statistics and analytical skills required to evaluate their results. The experience of writing the thesis is valuable and frequently leads to a peer-reviewed publication. The non-thesis track gives a strong coursework background in science and analysis, along with extensive internship experience that may lead more directly into a position.

Yes! In addition to what your agency or employer may offer, Military personnel and families can receive benefits through the  GI Bill, Yellow Ribbon Program, and more.
