Northern Arizona University

What you'll study

The programme is centred on independent, faculty‑mentored research and complemented by advanced coursework and professional development. Typical study areas include biomaterials and tissue engineering, biomechanics, synthetic and systems biology, bioinstrumentation, bioprocessing and synthetic biology, environmental and ecological bioengineering, and computational biology and bioinformatics.

Coursework normally covers advanced topics such as:

• Advanced Biomaterials and Tissue Engineering — material design, cell–material interactions and scaffold fabrication.
• Biomechanics — mechanics of biological tissues, experimental methods and modelling.
• Synthetic Biology and Systems Biology — genetic circuit design, metabolic engineering and network analysis.
• Bioinstrumentation and Sensors — design of biosensors, microfluidics and measurement systems.
• Bioprocessing and Biomanufacturing — scale‑up, fermentation and downstream processing principles.
• Computational Methods — modelling, data analysis, machine learning for biological data.
• Research Ethics and Responsible Conduct — ethical frameworks, regulatory issues and biosafety.

Programme structure typically combines a defined set of advanced courses, seminars and workshops, laboratory rotations or joining an existing research group, continuous research credit hours leading to a qualifying or comprehensive exam, and completion and defence of an original doctoral dissertation. Professional development modules frequently include grant writing, teaching practicum and communication skills for translating research to stakeholders.

Entry requirements

Applicants should hold a relevant graduate degree (master’s or equivalent) or a strong bachelor’s degree in engineering, biological sciences, chemistry, physics, or a closely related field, with a record of academic achievement. Typical application components include:

• Academic transcripts demonstrating relevant coursework and strong performance.
• A statement of research interests that aligns with departmental faculty expertise.
• Curriculum vitae highlighting research experience, publications or technical projects.
• Letters of recommendation, preferably from faculty or professional supervisors familiar with the applicant’s research potential.
• Evidence of quantitative and laboratory skills; prior research experience is strongly preferred.

Some applicants may be invited to interview with potential supervisors. International applicants must meet the university’s English language requirements. Specific departmental prerequisites or preparatory coursework may be required for candidates from non‑traditional backgrounds.

Career prospects

Graduates of a PhD in Biological Engineering pursue a wide range of careers. Common destinations include tenure‑track academic positions and postdoctoral research roles, where graduates continue fundamental or applied research. In industry, alumni work in biotechnology and pharmaceutical companies, medical device firms, environmental engineering consultancies, and start‑ups focusing on synthetic biology, diagnostics or biomanufacturing.

Other career paths include research scientist or R&D leadership roles in corporate and government laboratories, regulatory and translational science positions, technology transfer and intellectual property management, and specialist roles in data science and computational biology. The programme also provides training relevant for careers in science policy, entrepreneurship and higher‑education teaching.
