Georgetown University

What you'll study

The programme centres on advanced, hypothesis-driven research in areas such as microbial pathogenesis, viral and bacterial immunology, innate and adaptive immune mechanisms, host–pathogen signalling and microbial ecology. Training combines directed coursework, laboratory rotations and an independent dissertation project under the supervision of a faculty mentor.

• Core topics: cellular and molecular immunology, microbial genetics and physiology, host–pathogen interactions, and advanced molecular biology techniques.
• Typical modules and skills: advanced immunology, microbial pathogenesis, molecular methods (cloning, sequencing, CRISPR approaches), microscopy and imaging, proteomics and genomics approaches, bioinformatics fundamentals, and experimental design.
• Research training: initial lab rotations to identify a thesis laboratory, regular progress reporting, preparation of grant-style proposals, qualifying/comprehensive examinations, and dissertation research leading to a defended thesis.
• Professional development: training in research ethics, scientific communication, teaching opportunities, grant writing, and career preparation tailored to academic, industry and policy careers.

Entry requirements

Applicants are normally expected to hold a bachelor’s degree in biology, biochemistry, microbiology, immunology or a closely related discipline; many successful applicants also hold a relevant master’s degree. Strong laboratory research experience is essential, demonstrated by research projects, publications or substantial laboratory employment.

• Academic transcripts showing a strong foundation in core biological sciences and quantitative methods.
• A research statement describing past laboratory experience and proposed research interests, plus a personal statement outlining career goals.
• Letters of recommendation (typically three) from academic or professional referees who can evaluate research potential.
• Proof of English language proficiency for applicants whose first language is not English, as required by university regulations.
• Successful applicants may be invited to interview with prospective faculty; selection is based primarily on research fit and potential rather than standardized test scores.

Career prospects

Graduates of the PhD programme pursue a range of careers that leverage rigorous laboratory and analytical training. Many move into academic postdoctoral positions leading to faculty roles or independent research careers. Others transition to research scientist positions in pharmaceutical and biotechnology companies, where they contribute to drug discovery, vaccine development and translational research.

• Academic research and faculty positions
• Industry research roles in biotech and pharmaceutical companies
• Government and public health laboratories, regulatory agencies and national research institutes
• Clinical laboratory science, scientific communication, patent science and science policy
• Biotech start-ups and translational research organisations

Why study at Georgetown University

Georgetown’s programme is embedded within a major medical centre and benefits from close links to clinical departments, specialised core facilities and interdisciplinary centres focused on infectious disease and immunology. Students gain access to state-of-the-art laboratories, translational research opportunities and collaborative projects across basic science and clinical disciplines.

• Strategic location: being in Washington, D.C. creates opportunities for collaboration with federal research agencies, public health organisations and policy institutions.
• Faculty expertise: a diverse group of investigators working on viral and bacterial pathogenesis, immune regulation, vaccine development and host responses.
• Training environment: structured mentorship, a strong emphasis on responsible conduct of research, and professional development resources to prepare students for diverse scientific careers.
