Message from the Chair, Dr. Merri Lynn Casem

Merri Lynn CasemWelcome to the website of the Department of Biological Science at Cal State Fullerton. We offer an undergraduate Bachelor’s degree (B.S.) in Biological Science and a thesis-based Master of Science (M.S.) degree in Biology. 

We are dedicated to educating the individual student using active-learning, inquiry-based approaches. The undergraduate curriculum provides all biology majors with broad exposure to fundamental biological principles and depth of knowledge within a specialized area of concentration chosen by the student.

Our program is distinctive in the region in the number of excellent opportunities that are available for faculty-mentored undergraduate research and a commitment to integrating teaching and research. Our mission is to help guide students to acquire the skills, develop the attitudes, and master the information necessary to continue their education, obtain desirable employment in biology-related careers, and be productive citizens. 

Our graduate degrees prepare students for entry into Ph.D. and health-professions programs, research careers with governmental and non-governmental agencies and in the private sector, and teaching at the two-year college level.
