Biology, B.S.

Return to {$returnto_text} Return to: College of Arts and Sciences

Biology is a diverse discipline, encompassing the health sciences (medicine, dentistry, and veterinary science), biomedical research, agriculture, ecology, teaching, and more.  A major in biology from Saint Leo University is designed as preparation for a career in the exciting and rapidly changing field of the life sciences, whatever the sub discipline.  In the laboratory, classroom, and field, biology majors will build a firm foundation in life and physical sciences by exploring the facts, theory, and methodologies employed by scientists today.

Three curricular concentrations are available: students can follow the general curriculum (General Biology) and become broadly trained, or they can choose to focus their studies and select either the Biomedical Sciences and Health Professions concentration or the Ecology concentration.  All three options provide flexibility to students to craft a curriculum that fits their interests while still providing essential instruction in the life sciences, physical sciences, and mathematics necessary for success as a Biologist.
