Biology is the study of life, from vast continental and marine ecosystems to single microscopic cells. The primary goal of the Department of Biological Sciences at Cal State San Marcos is to help students develop the theoretical, practical, and analytical tools necessary to appreciate the breadth of biology and pursue their specific research interests and career goals. Toward this end, the department offers a diverse selection of small, student-centered courses taught by a faculty devoted to student success. In addition, Cal State San Marcos Biology students have exceptional opportunities to pursue cutting-edge research in well-equipped, modern laboratories. As early as their sophomore year, undergraduates are encouraged to participate in faculty-supervised research projects which provide practical experience in experimental design, data collection and analysis, and oral/written presentation of experimental findings. This experience gives our graduates the skills and knowledge to pursue careers in fields such as biotechnology, natural resources management, and biology education, as well as opportunities to pursue advanced or professional degrees in the life sciences.
