Why Biology at SDSU?

The Department of Biology at San Diego State University has excellent degree programs with courses taught by over 50 full-time, research-active faculty members. We serve and mentor approximately 1,300 undergraduate majors in Biology and Microbiology, 80 minors, 150 graduate students, and thousands of students from other departments. SDSU offers various coursework in cellular and molecular biology, ecology, evolution, and related fields. In a typical semester, undergraduates have access to over 50 courses. Nearly all of these classes are small, with fewer than 30 students, or have associated laboratory sections with fewer than 25 students.
