The Biochemistry B.S. prepares graduates for opportunities in biotechnology, pharmaceuticals and scientific research, while also providing a strong foundation for medical, dental, veterinary and graduate education. UC San Diego's official major information identifies alumni employment across organizations including Illumina, Cue Health, BioLegend, Thermo Fisher Scientific, Gilead Sciences, Eurofins and BD.
Typical career directions include: Biochemist, Research Assistant, Clinical Laboratory Technologist, Life Scientist.
Students can build their professional pathway through:
Career preparation: UC San Diego Career Services provides career-preparation resources and connects students with employers through career fairs, Handshake and related career programs. In the university's 2025–26 Career Fair data, employers reported recruiting for internships, early-career positions and graduate-level roles.
Employment outcomes: UC San Diego's First Destination Survey reports that 28% of respondents from the 2023–24 graduating class were employed full-time at graduation, while 27% were enrolled in a continuing-education program. Among employed respondents in the 2022–23 survey, 40% found their job as a result of an internship. These figures are university-wide rather than specific to Biochemistry B.S. graduates.
Salary information: UC San Diego publishes first-destination employment and compensation information through its First Destination Survey and Lightcast resources, but the official sources reviewed do not provide a Biochemistry B.S.-specific salary figure that can be reliably attributed to this program.
