University of San Diego

What you'll study

This PhD is centred on independent research that culminates in a doctoral dissertation, supported by a programme of advanced coursework, specialist electives and professional skills training. Core topics commonly studied include evolutionary theory, population genetics, phylogenetics and systematics, community and ecosystem ecology, quantitative ecology and ecological modelling. Students also take training in statistics and computational methods, experimental design, molecular laboratory techniques, field methods for population and community studies, and teaching pedagogy.

Typical components of the programme include:

• Advanced seminars in evolution, systematics and population biology that survey current literature and foster critical discussion.
• Methods courses covering population genetics, phylogenetic inference, ecological statistics, spatial analysis and modelling.
• Laboratory and field practicum providing hands-on experience in molecular methods, tagging and survey techniques, remote sensing and experimental manipulations.
• Research rotations or early-stage collaborative projects to help students refine dissertation topics and select advisors.
• Professional development modules such as grant writing, scientific communication, teaching experience and ethics in research.
• A qualifying or comprehensive examination to assess readiness to proceed to dissertation research, followed by original research and dissertation defence.

Entry requirements

Admission is competitive and intended for applicants with a solid foundation in biological sciences. Typical applicants hold a relevant master’s degree or a bachelor’s degree with substantial research experience. Admissions materials normally include official transcripts, a curriculum vitae, a personal statement outlining research interests, a research statement or writing sample, and three letters of recommendation. International applicants must demonstrate English language proficiency through an approved test unless exempt.

Successful candidates usually show evidence of prior research (published papers, conference presentations or substantive thesis work), quantitative skills (statistics, programming or modelling), and a clear fit with departmental faculty research interests. Specific documentation requirements and any standardised-test policies are provided by the university’s graduate admissions office.

Career prospects

Graduates of this PhD typically pursue careers in academia as postdoctoral researchers and faculty, where they continue fundamental and applied research in evolution, ecology and systematics. Other common pathways include research scientist roles in government agencies (wildlife, fisheries, environmental protection), non-governmental conservation organisations, ecological consulting, and industry positions related to biotechnology, environmental assessment and natural resource management.

PhD training also prepares graduates for roles in science policy, outreach and communication, museum and herbarium curation, and data-intensive positions that require advanced quantitative and computational skills. The programme’s emphasis on grant writing, teaching experience and interdisciplinary collaboration supports diverse career trajectories beyond traditional academic posts.

Why study at University of San Diego

The University of San Diego offers doctoral training within a small, research-focused environment with close faculty mentorship and opportunities for interdisciplinary collaboration. The university’s location in Southern California provides ready access to a wide range of terrestrial, coastal and marine ecosystems, enabling field-based research across diverse habitats and taxa.

Students benefit from dedicated laboratory and computational facilities, a curriculum that integrates molecular, organismal and quantitative approaches, and professional development resources to build teaching and grant-writing skills. Proximity to regional research centres, conservation organisations and governmental agencies creates opportunities for partnerships, internships and collaborative projects that enhance both applied and theoretical research outcomes.

Overall, the programme is well suited to students who want rigorous, mentor-led doctoral training with strong methodological grounding and opportunities to conduct field and laboratory research in a biologically diverse region.
