University of Arizona

What you'll study

This degree provides a foundation in core biological sciences before focusing on microbes, host–microbe interactions and immune system function. Early courses cover general biology, chemistry and statistics to build quantitative and experimental skills. Core microbiology and immunology modules explore microbial physiology, bacterial genetics, virology, parasitology, innate and adaptive immunity, and immunogenetics.

Practical and skills-led components are emphasised: laboratory methods in microbiology and immunology, molecular biology techniques (PCR, cloning, sequencing basics), microscopy, cell culture and sterile technique. Students typically complete laboratory courses with a mix of guided practicals and independent projects.

The programme encourages hands-on research through independent honours projects, capstone courses or placement in faculty laboratories. Electives allow specialisation in areas such as microbial ecology, infectious disease, vaccine biology, bioinformatics, clinical microbiology and public health microbiology. Opportunities for coursework in ethics, scientific communication, and regulatory aspects of biomedical science are also available.

Entry requirements

Applicants are expected to meet the University of Arizona's undergraduate admission standards and to have a strong background in science and maths from secondary education. Typical preparation includes:

• High school coursework in biology and chemistry; additional coursework in physics and mathematics (algebra, precalculus or calculus) is strongly recommended.
• Strong grades in science and mathematics subjects. Standardised test submission policies vary; consult the university for current guidance.
• International applicants should demonstrate equivalent academic preparation and satisfy English language proficiency requirements.
• Transfer applicants are welcome; successful transfers usually present college-level coursework in biology, chemistry and maths and a competitive GPA.

Many students strengthen their applications with extracurricular experience such as laboratory volunteering, science fairs, internships or relevant paid work. Prospective students interested in professional careers (medicine, dentistry, veterinary medicine) are advised to check additional prerequisite expectations for those pathways.

Career prospects

Graduates enter a range of careers across academia, healthcare and industry. Common roles include:

• Research technician or research assistant in university, government or private-sector laboratories.
• Clinical laboratory scientist (with additional certification/clinical training as required by jurisdiction).
• Biotechnology and pharmaceutical industry positions in product development, quality control, regulatory affairs or manufacturing support.
• Public health and epidemiology roles within local, state or national health departments and non-governmental organisations.
• Science communication, education and outreach roles at museums, schools or public agencies.

Many graduates continue to postgraduate study: PhD programmes in microbiology, immunology or related biomedical fields; professional degrees such as MD, DVM, or PharmD; or specialised masters-level training in public health, clinical laboratory science or biotechnology.
