University of San Diego

What you'll study

The programme provides a foundation in general biology and chemistry before progressing to specialised courses in microbiology and immunology. Core topics typically include cell and molecular biology, microbial physiology, virology, bacteriology, host–pathogen interactions, and mechanisms of innate and adaptive immunity.

• Foundational courses: general biology, organic and inorganic chemistry, introductory physics, and calculus or statistics.
• Core biological sciences: cell biology, genetics, molecular biology and biochemistry that underpin microbial and immune system function.
• Microbiology and immunology modules: microbial genetics, bacteriology, virology, immunology, microbial pathogenesis and laboratory techniques for culture, microscopy and molecular assays.
• Laboratory and research training: multi‑semester wet lab courses, molecular methods, lab safety and best practice, plus opportunities for independent research projects or a senior capstone in faculty laboratories.
• Quantitative and computational skills: biostatistics, data analysis, bioinformatics or computational biology electives to support modern experimental design and interpretation.
• Electives and interdisciplinary options: courses in public health, epidemiology, pharmacology, environmental microbiology, and ethics to broaden application of microbiological and immunological knowledge.

The curriculum balances lectures with hands‑on laboratory experience and emphasises critical thinking, experimental design and scientific communication. Students are encouraged to engage in undergraduate research with faculty, internships with local hospitals or biotech firms, and study abroad or service‑learning experiences.

Entry requirements

Entry to the programme follows the University of San Diego's undergraduate admissions process. Successful applicants typically present a strong high school academic record with coursework in biology, chemistry and mathematics. Prior laboratory experience is advantageous but not always mandatory.

• Academic background: high school diploma or equivalent with competitive grades; recommended subjects include biology, chemistry (often including a year of chemistry with labs), mathematics (algebra and precalculus or calculus) and physics.
• Standardised testing: the university's admissions policy on tests may be flexible; consult the admissions office for current guidance on SAT/ACT submission.
• Supporting materials: personal statement or application essay, letters of recommendation (teachers or mentors), and a résumé of extracurricular activities, research or volunteer work.
• International applicants: proof of English proficiency through recognised tests unless exempt; academic transcripts should be translated and evaluated as required.
• Transfer students: applicants transferring from other institutions should supply college transcripts and details of completed science coursework; articulation agreements and transfer credit evaluations are handled by the registrar.

Career prospects

Graduates with a BSc in Microbiological Sciences and Immunology go on to a range of careers across academia, industry and public service. Many pursue further training or professional degrees; others enter the workforce directly in technical or applied roles.

• Research laboratory technician or associate in academic, government or commercial laboratories.
• Clinical laboratory scientist or technologist (may require additional certification or training depending on jurisdiction).
• Positions in biotechnology and pharmaceutical companies, including quality control, regulatory affairs, production and R&D support roles.
• Public health and epidemiology roles at local, state or national health agencies, or in non‑profit organisations.
• Further study leading to master's or doctoral research degrees (MS/PhD) in microbiology, immunology, molecular biology or related fields, as well as professional programmes in medicine, dentistry, veterinary medicine or physician assistant studies.
• Science communication, education and outreach roles, or positions in environmental microbiology and food safety.

Why study at University of San Diego

The University of San Diego offers a personalised undergraduate education with relatively small class sizes and close faculty mentoring. The Biology department has active research programmes that provide undergraduates with opportunities to join labs and gain authentic research experience.

• Research opportunities: access to faculty‑led labs, summer research programmes and the chance to undertake independent projects or a senior capstone.
• Facilities and location: modern teaching and research laboratories and proximity to San Diego's vibrant biotech and biomedical community, which supports internships and industry collaborations.
• Interdisciplinary environment: collaboration across departments—for example with chemistry, engineering and public health—allows students to tailor degrees to specific career goals.
• Supportive campus culture: advising, career services and alumni networks that help students prepare for graduate study and professional placement.
• Values and community engagement: a commitment to ethical practice, service learning and global perspectives consistent with the university's mission.
