University of California

What you'll study

This PhD combines advanced coursework, methodological training and an independent research programme centred on animal health, zoonoses and their interface with human public health. Core study areas include epidemiologic study design, infectious disease dynamics, biostatistics and statistical modelling, spatial epidemiology and surveillance systems. Elective and specialised topics typically cover pathogen genomics and phylogenetics, quantitative risk assessment, antimicrobial resistance, vaccine impact evaluation, diagnostic test evaluation, One Health policy and ecosystem health.

Programme structure commonly includes initial coursework to build depth in epidemiology and quantitative methods, a qualifying or comprehensive examination, a supervised original research project leading to a doctoral dissertation, and opportunities to teach or mentor junior students. Research training emphasises field study design, data collection and management, advanced analysis (including bayesian and mechanistic models), and science communication to public health stakeholders.

• Core methods: epidemiologic methods, advanced biostatistics, infectious disease modelling
• Applied topics: disease surveillance, outbreak investigation, zoonoses and One Health
• Laboratory and analytic tools: molecular epidemiology, GIS and spatial analysis, diagnostic test evaluation
• Professional skills: grant writing, policy translation, teaching and leadership in interdisciplinary teams

Entry requirements

Applicants are normally expected to hold a recognised relevant master's degree or a DVM/MD with substantial quantitative training, or in some cases an outstanding bachelor's degree with significant research experience. Typical backgrounds include veterinary medicine, epidemiology, public health, biology, ecology or statistics. Admissions committees look for demonstrated research potential through previous theses, publications or substantial research employment, strong letters of recommendation, a clear research statement aligned with faculty expertise, and quantitative competence.

English language proficiency is required for applicants whose first language is not English. Applicants should contact potential supervisors in advance to discuss fit and available funding; admission is often linked to faculty research programmes. Specific documentation requirements and any standardised test policies are listed on the programme’s official admissions pages.

Career prospects

Graduates are prepared for research-intensive and leadership roles across academia, government and industry. Typical career paths include university faculty positions and postdoctoral research in veterinary epidemiology, roles in national and international public health agencies (such as animal health and food safety authorities), work with international organisations and NGOs on disease surveillance and control, and positions in pharmaceutical or diagnostic companies focused on animal and zoonotic diseases.

Other opportunities include positions in environmental and wildlife health agencies, consultancy in risk assessment and preparedness, and leadership roles in One Health initiatives that bridge animal, human and ecosystem health. The programme’s emphasis on quantitative skills, field methods and science–policy translation equips graduates to influence disease control programmes, policy development and emergency response planning.

Why study at University of California

The University of California offers a strong environment for veterinary epidemiology and public health research through its veterinary medicine and public health units, interdisciplinary One Health initiatives, and extensive laboratory and field resources. Students benefit from collaborations across animal health, public health, environmental science and genomics, access to clinical case material and field sites, and established partnerships with government and international health agencies.

Doctoral candidates are typically supported by active research groups, access to statistical and bioinformatics core facilities, and opportunities to engage in applied outbreak investigations and policy-relevant projects. The collegiate research environment emphasises mentorship, cross-disciplinary training and preparing graduates to address complex animal–human–environment health challenges at local, national and global scales.
