Case Western Reserve University

What you'll study

This PhD programme combines advanced coursework with intensive laboratory research. Early-stage training typically includes core graduate courses in molecular microbiology, microbial genetics, virology, immunology (innate and adaptive), experimental design and quantitative methods. Students participate in laboratory rotations to identify a thesis laboratory, and take specialised elective modules in areas such as bacterial pathogenesis, host–microbe interactions, mucosal immunology, microbial ecology and systems immunology.

Programme components commonly include:

• Core coursework in molecular and cellular mechanisms of microbes and immune cells
• Laboratory rotations to gain hands‑on experience in different research groups
• Regular research seminars, journal clubs and departmental colloquia
• Responsible conduct of research and training in statistics and experimental design
• Qualifying examinations that assess readiness to undertake independent research
• Original thesis research leading to a defence and peer‑reviewed publications

Research areas

• Bacterial and viral pathogenesis
• Host innate and adaptive immune responses
• Microbiome and host–microbe interactions
• Antimicrobial resistance and pathogen evolution
• Immunotherapy, vaccine development and translational immunology
• Structural and systems approaches to microbial and immune biology

Entry requirements

Applicants are expected to hold a strong undergraduate degree (or equivalent) in biology, microbiology, immunology, biochemistry or a related discipline. A completed master's degree with research experience strengthens an application but is not always required if the applicant has significant undergraduate research experience.

• Evidence of prior laboratory research, usually demonstrated by a research project, publications or detailed reference letters
• Academic transcripts showing strong performance in relevant coursework
• Three professional letters of recommendation from supervisors or academic referees
• A personal statement describing research interests, relevant experience and proposed directions for doctoral study
• Curriculum vitae detailing laboratory skills and techniques
• For applicants whose first language is not English, an approved English language proficiency test may be required

The programme evaluates applicants holistically; specific test requirements (such as any standardised tests) and funding arrangements should be confirmed on the university’s graduate admissions pages. Prospective students are encouraged to contact potential faculty mentors before applying.

Career prospects

Graduates of this PhD frequently follow research careers in multiple sectors. Common pathways include academic postdoctoral training leading to faculty positions, research scientist roles in biotechnology and pharmaceutical companies, and positions in translational research within hospital or clinical research centres. Other career destinations include clinical and public‑health laboratories, regulatory agencies, science policy, patent law (with additional training), and science communication.

Training emphasises independent research, technical proficiency across contemporary molecular and immunological methods, data analysis and scientific communication — skills valued by employers in both basic and applied bioscience settings.
