Case Western Reserve University

What you'll study

This PhD emphasises original research combined with advanced coursework in ecology, evolutionary biology, systematics and population biology. Typical coursework and training areas include:

• Foundations of evolutionary theory: population genetics, quantitative genetics, molecular evolution and speciation.
• Ecological theory and practice: community and ecosystem ecology, behavioural ecology, landscape ecology and population dynamics.
• Systematics and phylogenetics: comparative methods, phylogenetic inference, taxonomy and integrative approaches to species delimitation.
• Methods and quantitative skills: statistics for ecology and evolution, computational modelling, bioinformatics, genomic data analysis and experimental design.
• Field and laboratory techniques: design and execution of field experiments, long‑term monitoring, molecular lab work and trait measurement protocols.
• Professional development: scientific communication, grant writing, teaching practicum and ethics in research.

Students usually take a mix of core and elective courses in the first 1–3 years, participate in regular seminars and lab group meetings, pass a qualifying examination or proposal defence, and then proceed to dissertation research under the supervision of one or more faculty advisers. Interdisciplinary collaborations and coursework with related departments are encouraged to support diverse methodological approaches.

Entry requirements

Applicants are expected to have a strong academic record in biology or a closely related field. Typical requirements include:

• A bachelor’s degree in biology, ecology, evolution, genetics, or related disciplines; applicants with a relevant master’s degree are also welcome.
• Demonstrated research experience (undergraduate or postgraduate research projects, publications, or substantive laboratory/field work).
• A curriculum vitae, statement of research interests outlining proposed PhD directions, and academic transcripts.
• Letters of recommendation from faculty or research supervisors who can speak to the applicant’s research potential.
• Proof of English proficiency for international applicants where required.

The programme evaluates applicants holistically, placing strong emphasis on research fit with faculty expertise and evidence of quantitative and experimental skills. Admissions policies regarding standardised tests and other materials may change, so applicants should consult the programme for current details.

Career prospects

Graduates from this PhD programme move into a variety of careers that build on advanced research and quantitative skills. Common career paths include:

• Academic positions (postdoctoral fellowships, university faculty, research scientists) conducting independent research and teaching.
• Government and public sector roles in biodiversity monitoring, wildlife and fisheries management, conservation planning and environmental regulation.
• Applied research and technical roles in non‑profit conservation organisations, environmental consultancies and museums.
• Industry positions in biotechnology, agricultural research, ecological modelling and data science where expertise in genomics and quantitative modelling is valued.
• Science communication, policy advising and roles that translate ecological and evolutionary knowledge into public decision making.

The programme’s emphasis on interdisciplinary and quantitative training prepares graduates for positions that require data analysis, large‑scale synthesis and experimental design.

Why study at Case Western Reserve University

Case Western Reserve University offers an environment that combines strong faculty mentorship with access to rich urban and regional research resources. Faculty in ecology, evolution and systematics pursue research across molecular to landscape scales, providing students with a range of methodological and topical mentorship.

Students benefit from collaborations with nearby institutions and resources — including natural history collections, regional field sites and Great Lakes ecosystems — which support fieldwork and comparative studies. The university also provides core facilities for molecular and genomic work, computational support for large data sets and opportunities for interdisciplinary collaboration with other departments and centres.

Doctoral candidates gain teaching experience, participate in departmental seminars and receive support for professional development and grant applications, helping to prepare them for diverse careers in research, conservation and applied biological sciences.
