University of San Diego

What you'll study

This programme provides advanced instruction in evolutionary biology, population genetics, phylogenetics, systematics, and ecological theory, with emphasis on both empirical and quantitative approaches. Typical core topics include evolutionary theory and speciation, population and quantitative genetics, phylogenetic methods and molecular systematics, community and ecosystem ecology, ecological modelling, and experimental and observational field methods.

Students combine coursework with hands‑on laboratory and fieldwork. Practical training often covers molecular techniques (DNA sequencing and genotyping), bioinformatics and comparative analyses, statistics for ecological and evolutionary data, and the design and implementation of field studies in coastal, chaparral and marine‑influenced environments typical of the San Diego region.

The degree is research oriented: students normally complete a supervised research thesis that culminates in a written dissertation and an oral defence or seminar. Seminars, journal clubs and departmental colloquia complement research skills by exposing students to current literature, grant writing, data presentation and professional development.

Entry requirements

• Bachelor’s degree in biology, ecology, environmental science, or a closely related discipline from an accredited institution, with a record of strong undergraduate performance.
• Official academic transcripts and a personal statement describing research interests and career goals, including identification of potential faculty mentors where possible.
• Two to three academic or professional letters of recommendation that can speak to the applicant’s research potential and academic preparedness.
• Demonstrated quantitative competency; coursework in genetics, ecology, statistics, or molecular biology is typically expected. Applicants with limited preparation may be admitted conditionally and asked to complete prerequisite coursework.
• International applicants must demonstrate English language proficiency through accepted tests or other institutional waivers if applicable.
• Additional materials that may strengthen an application include a CV, sample of written work (such as a lab report or honours thesis), and descriptions of past research experience. Specific test requirements (such as the GRE) and application policies are available from the university and can vary over time.

Career prospects

Graduates enter a range of careers in research, conservation and applied environmental science. Common pathways include pursuing a PhD in evolutionary biology, ecology or related fields; research scientist or post‑baccalaureate technician roles in university, government or private laboratories; and positions with conservation NGOs, natural resource agencies, and environmental consulting firms.

Other career options include wildlife and habitat management, biodiversity assessment and monitoring, environmental impact analysis, science communication and policy advising, and roles in biotech or bioinformatics companies where skills in molecular methods and data analysis are valued. The programme’s emphasis on field techniques and quantitative analysis also prepares graduates for roles in long‑term ecological research and database curation.

Why study at University of San Diego

• Location advantage: USD’s location in Southern California provides ready access to a wide range of study habitats — coastal, marine‑influenced, chaparral and riparian systems — enabling diverse field projects within driving distance.
• Faculty mentorship: the programme’s smaller cohort size encourages close mentoring relationships with faculty, facilitating hands‑on research supervision and tailored training plans.
• Practical facilities and training: students gain experience with contemporary molecular, statistical and computational tools, and undertake fieldwork using regional sites and facilities that support ecological and evolutionary research.
• Regional collaborations and internships: proximity to a strong local scientific community and conservation organisations creates opportunities for internships, collaborative research and applied conservation projects.
• Professional development: the curriculum integrates seminars, grant and manuscript preparation guidance, and presentation opportunities to prepare students for careers in academia, government and the private sector.
