University of North Carolina at Chapel Hill

What you'll study

This PhD programme combines advanced coursework, laboratory rotations and an extended independent research project leading to a doctoral dissertation. Early in the programme students typically complete core courses in molecular microbiology, cellular and molecular immunology, microbial genetics and host–pathogen interactions, together with statistics and experimental design. Coursework emphasises contemporary techniques such as high‑throughput sequencing, flow cytometry, advanced microscopy, bioinformatics and immunophenotyping.

Students usually undertake laboratory rotations across different faculty groups to identify a dissertation mentor and to broaden technical experience. After selecting a laboratory, students develop a written dissertation proposal and pass a qualifying or candidacy examination. The remainder of the programme is focused on hypothesis‑driven research, publication of results in peer‑reviewed journals and presentation at national and international conferences.

• Typical modules and topics: microbial pathogenesis, innate and adaptive immunity, immunogenetics, host–microbe interactions, vaccine immunology, microbial ecology and the microbiome, advanced molecular techniques, computational methods for biological data.
• Research training: laboratory rotations, dissertation research, grant writing workshops, teaching or mentoring opportunities, journal clubs and seminar series.
• Assessment: coursework and exams, qualifying/candidacy exam, dissertation proposal, original research judged by an advisory committee and final oral defence.

Entry requirements

Applicants should hold a bachelor’s degree in biology, microbiology, biochemistry, immunology or a closely related life sciences field. Many successful applicants also have a research master’s degree or substantial undergraduate research experience. Admissions look for evidence of laboratory skills, clarity of research interests, and potential for independent research.

• Academic preparation: strong academic record in relevant science subjects; substantial coursework in molecular biology, genetics, cell biology and immunology is advantageous.
• Research experience: prior laboratory experience with a demonstrated commitment to research, such as undergraduate honours projects, research assistant positions, or publications.
• Application documents: academic transcripts, curriculum vitae, statement of purpose outlining research interests, and at least three letters of recommendation from academic or research supervisors.
• Standardised tests and English language: policies on standardised tests (such as the GRE) and English language requirements vary; applicants should consult the department for current requirements and permitted alternatives.

Career prospects

Graduates of the programme go on to careers across academia, industry and government. Typical pathways include postdoctoral research positions and faculty roles in universities and medical schools; research scientist, principal scientist or R&D positions in biotechnology and pharmaceutical companies; roles in clinical and diagnostic laboratories; and research or leadership positions in public health agencies and non‑profit research organisations.

Skills developed in the programme—experimental design, advanced laboratory techniques, data analysis, scientific communication and grant writing—also prepare graduates for translational research, science policy, intellectual property and biotechnology entrepreneurship.
