Northern Arizona University

What you'll study

The MS in Biology at Northern Arizona University offers both thesis and non‑thesis options and combines coursework, laboratory training and field research. Core subject areas typically include ecology and conservation biology, evolutionary biology, molecular and cellular biology, organismal physiology, and quantitative methods such as biostatistics and experimental design. Students usually take a mix of seminar courses, advanced topical lectures and practical skills modules in molecular techniques, ecological methods, GIS and data analysis.

• Advanced seminars in ecology, evolution or physiology
• Molecular ecology and genomics techniques (e.g. DNA sequencing, PCR, population genetics)
• Field methods in terrestrial and aquatic ecology, including study design and monitoring
• Quantitative methods: biostatistics, ecological modelling and GIS applications
• Professional development: scientific communication, grant writing and ethics
• Thesis research project (for thesis option) or a capstone/project and additional coursework (for non‑thesis option)

Students work closely with faculty advisors to develop an individualized programme of study and research that aligns with faculty expertise. Fieldwork opportunities exploit the unique landscapes around Flagstaff and the Colorado Plateau, while laboratory research draws on the university's molecular and microscopy facilities.

Entry requirements

Applicants are expected to hold a recognised bachelor's degree in biology or a closely related discipline. Typical admissions considerations include a solid academic record, relevant undergraduate coursework (for example in genetics, ecology, biochemistry and statistics), and demonstrated research or practical experience.

• Official transcripts from all post‑secondary institutions attended
• Statement of purpose outlining research interests and career goals
• Letters of recommendation, usually two to three, from academic or professional referees
• Curriculum vitae or résumé detailing relevant experience
• International applicants must demonstrate English language proficiency through recognised tests unless exempt

Some specialisations or faculty mentors may expect prior laboratory or field experience. Admissions may consider applicants from related backgrounds who show strong preparation in quantitative and biological fundamentals. Standardised tests are not universally required; applicants should consult the programme for current testing policies.

Career prospects

Graduates of the MS in Biology pursue a range of careers across academia, government, non‑profit conservation, and industry. Common roles include research technician, laboratory manager, conservation biologist, wildlife biologist, environmental consultant, ecological modeller, and science educator. The degree also provides a solid foundation for students who wish to continue to doctoral study (PhD) or to professional programmes in related fields.

Employers of alumni typically include environmental and natural resource agencies, research institutions, universities, environmental consultancies, public health laboratories, and biotechnology companies. The programme’s emphasis on fieldwork, molecular methods and quantitative skills helps graduates meet the technical demands of contemporary biological careers.

Why study at Northern Arizona University

Northern Arizona University is well suited to students who want intensive field and laboratory experience within a research‑active department. Located in Flagstaff, the university provides access to a wide variety of ecosystems—from montane forests to high desert and nearby national parks—facilitating hands‑on studies in ecology, conservation and biogeography.

• Research strengths across ecology, evolutionary biology, conservation genetics, and physiology with faculty engaged in regional and global projects.
• Access to field stations and diverse study sites on the Colorado Plateau, supporting extended field seasons and habitat‑scale research.
• Laboratory infrastructure for molecular biology, microscopy and analytical support, plus GIS and quantitative training resources.
• Opportunities for funding and professional development through teaching assistantships, research assistantships and departmental support.
• Relatively small graduate cohorts that enable close mentorship and collaborative research with faculty.

Overall, NAU offers a balance of rigorous academic training and practical experience, preparing graduates for applied roles in environmental science and for further research training.
