Florida International University

What you'll study

The PhD in Biology at Florida International University combines advanced coursework, original research and professional development. Students undertake a customised programme of graduate seminars and core courses that typically cover molecular and cellular biology, organismal biology, ecology and evolution, quantitative methods, and bioinformatics. Training emphasises experimental design, statistical analysis, and scientific communication.

• Coursework and seminars — advanced topics such as molecular genetics, developmental biology, ecology, population genetics, systems biology, computational biology and methods in experimental design.
• Laboratory and field research — students conduct sustained research in faculty laboratories or in field settings; FIU’s south Florida location supports marine, coastal and wetland studies as well as tropical and subtropical ecological research.
• Research rotations — early-stage rotations (where available) help students identify a dissertation advisor and gain experience across different labs and techniques.
• Qualifying and comprehensive examinations — students complete written and/or oral qualifying exams to demonstrate mastery of foundational knowledge and prepare a dissertation proposal.
• Doctoral dissertation — original research presented in a written dissertation and defended orally before a faculty committee; publication in peer-reviewed journals is strongly encouraged.
• Professional development — opportunities in grant writing, teaching, public outreach, data management and responsible conduct of research.

Entry requirements

Applicants are expected to hold a strong bachelor’s degree in biology or a closely related discipline; a relevant master’s degree is typically preferred but highly qualified applicants with substantial research experience and a strong undergraduate record will also be considered. Competitive applicants demonstrate prior laboratory or field research, clear potential for independent investigation, and a coherent research interest aligned with faculty expertise.

• Academic transcripts — official transcripts showing a strong undergraduate or graduate record in biological sciences or related fields.
• Research experience — evidence of hands-on laboratory or field work, publications, conference presentations or substantial project work is important.
• Letters of recommendation — typically three academic or professional references who can speak to research potential and preparedness for doctoral study.
• Statement of purpose — a research statement outlining interests, past experience, and how the applicant’s goals fit with FIU faculty and resources.
• CV — detailing education, research experience, technical skills, publications and presentations.
• English language proficiency — required for applicants whose first language is not English; acceptable tests and minimum scores are set by the university.
• Standardised tests — some programmes may not require GRE scores or treat them as optional; applicants should check current departmental guidance.

Career prospects

Graduates of the PhD in Biology follow diverse career paths. Many pursue postdoctoral research and academic careers as faculty or research scientists. Others move into research positions in industry (biotechnology, pharmaceuticals, environmental consulting), government agencies (wildlife, public health, environmental protection), non-profit conservation organisations, or scientific policy and administration. Additional roles include science communication, patent and regulatory affairs, and data science roles that use quantitative biological skills.
