Idaho State University

What you'll study

The PhD in Biology is focused on independent research leading to a dissertation, supplemented by advanced coursework and professional development. Students undertake in-depth study in areas such as molecular and cellular biology, genetics and genomics, microbiology, physiology, ecology and evolutionary biology, conservation biology, and applied environmental and biomedical science.

Coursework typically includes advanced seminars, specialised elective modules, and research methods training in statistics, experimental design and bioinformatics. Early in the programme students work closely with a faculty advisor to develop a research plan; many programmes expect students to complete a qualifying examination or proposal defence before full acceptance into candidacy. The degree culminates in the execution of original research, preparation of a written dissertation, and a public dissertation defence.

• Advanced seminars in chosen specialism
• Research methods and statistics for biological research
• Molecular techniques, genomics and bioinformatics (programme-dependent)
• Field methods and ecological experimental design (for ecology-focused projects)
• Teaching practicum or assistantship experience
• Dissertation research and defence

Entry requirements

Applicants are expected to hold a bachelor’s degree in biology or a closely related field; many applicants hold a relevant master’s degree. Successful candidates typically demonstrate strong academic preparation in core biological sciences, laboratory or field research experience, and clear research interests aligned with faculty expertise.

Required application materials normally include academic transcripts, a statement of research interests or personal statement, a curriculum vitae, and letters of recommendation. Prospective students are encouraged to identify potential faculty advisors before applying and to discuss fit with research groups. International applicants must demonstrate English language proficiency in accordance with university policy.

The programme reviews applications holistically; funding and availability of a faculty sponsor are important factors in admission.

Career prospects

Graduates of the PhD in Biology pursue a wide range of careers. Many progress to postdoctoral positions and academic faculty roles, where they continue independent research and teaching. Others move into research scientist positions in government laboratories, environmental agencies, health and biomedical research organisations, and industry, including biotechnology and pharmaceuticals.

Additional career paths include roles in conservation and natural resource management, science policy, regulatory science, science communication and education, laboratory management, and consultancy. The doctoral training emphasises analytical skills, experimental design, data analysis and scientific communication, all of which are valued across research-intensive and applied careers.
