Students applying to the M.S. program may do so for reasons similar to those applying to the M.A. program but will also gain experience in laboratory research under guidance of a faculty mentor. This track emphasizes training in experimental design, interpretation of data and scientific writing, and requires a formal research project and thesis. An M.S. degree can prepare you to conduct research at universities, private companies and government labs, or to enter a Ph.D. program.

Biology students at SLU have access to excellent facilities on campus and at the University's Reis Biological Station. Collaborations with neighboring institutions such as Washington University in St. Louis, the University of Missouri St. Louis, the Missouri Botanical Garden, the Saint Louis Zoo and the Danforth Plant Science Center further expand possibilities for research and learning.

Alumni from SLU’s biology program have gone on to careers as teachers, university faculty and research scientists at pharmaceutical companies and government agencies.
