University of San Diego

What you'll study

The PhD in Biology emphasises original research alongside advanced coursework and professional development. Early in the programme students typically complete core graduate courses in subjects such as advanced molecular and cellular biology, quantitative ecology and evolution, experimental design and statistics, and specialised seminars in contemporary topics. Training also includes laboratory rotations or short-term research placements that help students identify an appropriate dissertation laboratory and adviser.

After coursework and passing a qualifying or comprehensive examination, students concentrate on an independent research project that culminates in a written dissertation and oral defence. Typical research areas represented among faculty and students include molecular and cellular mechanisms of disease, immunology and microbiology, developmental and systems neuroscience, population and community ecology, evolutionary biology, and marine and environmental biology. Students have opportunities to learn and apply techniques such as genomic and transcriptomic analysis, advanced microscopy, bioinformatics and modelling, field methods for ecology and conservation, and physiological and behavioural assays.

Professional development is integrated into the programme through journal clubs, teaching apprenticeships, grant-writing workshops, and opportunities to present at conferences. Students also have access to core research facilities such as microscopy suites, genomics and sequencing platforms, and experimental animal and aquatic facilities.

Entry requirements

Applicants are ordinarily expected to hold a bachelor’s degree in biology or a closely related discipline; applicants with a master’s degree or substantial research experience are strongly preferred. Typical minimum academic preparation includes undergraduate coursework in cell and molecular biology, genetics, ecology/evolution, biochemistry and statistics. Demonstrable laboratory experience and a track record of research (for example, research assistantships, honours theses, or publications) are important for a competitive application.

Application materials usually include academic transcripts, a detailed curriculum vitae, a personal statement outlining research interests and career goals, and contact information for referees who can comment on the applicant’s research potential. International applicants must meet the university’s English language proficiency requirements. GRE submission policies may vary, so applicants should confirm current requirements before applying.

Career prospects

Graduates of the PhD in Biology pursue a range of careers in academia, industry, government and the non-profit sector. Common career paths include tenure-track faculty positions, postdoctoral research appointments, research scientist roles in biotechnology and pharmaceutical companies, and research or policy roles in government agencies and environmental organisations. Graduates also move into science communication, technology transfer, patent law (with additional training), and leadership roles in conservation and public health.

The programme’s emphasis on rigorous research training, quantitative skills and professional development prepares students for careers that require independent experimental design, grant writing and scientific leadership.
