Master of Science in the Field of Biological Sciences (STEM)

Beginning in fall 2025, the Department of Biological Sciences will offer three concentrations for students in the MS in biological sciences program. Students must select and apply for one of these concentrations, which are described below.

This is a highly interactive master's program drawing on the department’s research strengths spanning the areas of systematics, evolution, ecology as well as cellular and molecular biology. Students who wish to enhance their knowledge of a specific area of biology while gaining additional quantitative analysis and laboratory skills through applied courses can apply to either the biodiversity science concentration or the cellular and molecular biology concentration. A third thesis-based concentration option allows students to pursue research in the laboratory of an advisor identified at the time of admission. Students in the program often take advantage of other researchers, faculty, and facilities at GW and elsewhere in the Washington area. These include the National Institutes of Health (NIH) and Smithsonian Institution’s National Museum of Natural History.

Biodiversity Science Concentration (non-thesis)

Amid increasing concern about the health of ecosystems and endangered species, expertise in biodiversity science allows students to specialize in the principles and methods of comparative biodiversity science. Students in this track explore the complexities of evolution over time, the ecological interactions of species with each other and the environment, and potential biological indicators of ecosystem disturbances.

Cellular and Molecular Biology Concentration (non-thesis)

Graduate students in the cellular and molecular biology focus area prepare for real-world challenges through research on well-studied model systems, non-model organisms, and comparisons among different types of organisms. Students in the program will gain advanced laboratory and statistical analytical skills. The program will prepare students for research and laboratory-based careers as well as medical and MD/PhD programs.

Research Lab Thesis-Based Concentration

This concentration allows students to pursue research in the laboratory of an advisor identified at the time of admission in one of two broad areas: cell and molecular biology or systematics, evolution, and ecology. Aimed at those who seek additional graduate work such as for a PhD, coursework is tailored to the student’s research interests and it also requires the successful completion and defense of a written research thesis. To complement their classroom education, students can get involved in ongoing field research at both terrestrial and aquatic field sites around the world.  Students must contact faculty prior to application to this concentration to inquire whether faculty are taking students on in their lab.

This is a STEM designated program.
