Doctor of Philosophy (Ph.D.)
Location(s): Foggy Bottom - Main Campus

Program Overview

Program Overview

The PhD in Microbiology and Immunology program provides flexible, rigorous training that prepares students to become independent research scientists in the areas of molecular virology, molecular parasitology and immunology.

The program begins with interdisciplinary coursework in genes, cells and systems in biomedical sciences, professional development in scientific communication and science careers, and laboratory rotations offered through GW’s Institute for Biomedical Sciences. After the first year of study, students work with their research advisor to complete remaining degree requirements, including the dissertation.

Faculty are drawn largely from the GW School of Medicine and Health Sciences, including scientists from Children’s Research Institute of Children’s National Health System. Research strengths and training opportunities include the study of host-pathogen relationships, inflammation, vaccine development, T lymphocyte activation, cancer immunology, molecular parasitology, molecular retrovirology (HIV/AIDS), and microbial genomics and proteomics.

Students have access to extensive research facilities and libraries on campus and in the greater Washington, D.C., area, which include the School of Medical and Health Sciences, GW’s Gelman Library and Himmelfarb Health Sciences Library, Children’s Research Institute, the National Institutes of Health and numerous other research institutions.
