Indiana University Bloomington

What you'll study

The programme emphasises laboratory research complemented by advanced coursework in microbiology, immunology, molecular biology and quantitative methods. Early in the degree students complete core and elective modules, rotate through laboratories to find a dissertation adviser, and then concentrate on an independent research project leading to a doctoral thesis.

• Core topics: microbial physiology and genetics, innate and adaptive immunity, host–pathogen interactions, microbial ecology, and molecular microbiology.
• Typical modules and seminars: advanced bacteriology and virology, cellular and molecular immunology, microbial genomics and bioinformatics, experimental design and statistics, and special-topic journal clubs/seminars.
• Research training: laboratory rotations, formulation of a dissertation proposal, qualifying/ comprehensive examinations, and continuous thesis research under faculty supervision.
• Skills development: experimental design, advanced microscopy and flow cytometry, next‑generation sequencing and computational analysis, grant writing, and scientific communication including teaching experience or mentoring.

Students are expected to design and carry out an original research programme, present findings at internal and external meetings, publish in peer‑reviewed journals and defend a written dissertation. Interdisciplinary collaboration with other departments and access to shared core facilities support diverse project types from molecular mechanism studies to systems‑level investigations.

Entry requirements

Successful applicants typically hold a strong bachelor’s degree in biology, microbiology, immunology or a closely related field; many hold a relevant master’s degree and significant laboratory research experience. Selection is based on research potential and fit with faculty interests.

• Academic background: upper‑division honours or equivalent in biological sciences; prior coursework in genetics, cell biology, biochemistry and statistics is expected.
• Research experience: demonstrated hands‑on laboratory experience and independent project work (undergraduate thesis, master's research or equivalent) are highly desirable.
• Application materials: academic transcripts, curriculum vitae, statement of research interests, and names of referees or letters of recommendation.
• English language: applicants whose first language is not English must meet the university’s English proficiency requirements.

Standardised tests or other requirements may vary; prospective students should consult the programme’s admissions guidance and contact potential faculty advisers to discuss research fit before applying.

Career prospects

Graduates from the PhD programme pursue a wide range of careers. Many continue in research as postdoctoral scholars and then as faculty in universities and medical schools. Others move into research scientist roles in biotechnology and pharmaceutical companies, clinical and public‑health laboratories, or governmental and non‑governmental research organisations.

• Academic research and teaching (tenure‑track and research faculty)
• Industry research and development (biotech, pharma, diagnostics)
• Public health, clinical microbiology and epidemiology
• Science policy, regulatory science and intellectual property
• Science communication, research management and technical consulting

The programme’s emphasis on rigorous experimental training and quantitative skills also prepares graduates for careers in computational biology, bioinformatics and data‑driven biotechnology enterprises.

Why study at Indiana University Bloomington

Indiana University Bloomington offers a research‑intensive environment with access to experienced faculty working across microbial sciences and immunology. The campus provides well‑equipped core facilities—such as genomics, imaging and flow cytometry centres—that support modern experimental approaches.

• Collaborative environment: interdisciplinary links across biological sciences, computational biology and related centres foster cross‑disciplinary projects.
• Faculty mentorship: students are paired with research advisers whose laboratories cover diverse model systems and techniques, enabling tailored dissertation projects.
• Professional development: opportunities for teaching, grant writing and conference participation help build the skills needed for academic and non‑academic careers.

The programme is designed for students seeking rigorous scientific training, close faculty mentorship and an environment that supports both fundamental and applied research in microbiology and immunology.
