Biological Sciences

The study of Biological Sciences at St. Mary’s University includes a broad-based curriculum and extensive scientific training designed to prepare well-rounded health care professionals, teachers and scientists.

Students develop written and oral communication skills, as well as critical thinking and analytical skills. In addition, students obtain an understanding and respect for ethical and moral concerns.

Because our students display competence, dedication and compassion, they are readily accepted into graduate programs, the health professions, biomedical research and teaching fields.

For freshman Biology majors interested in a career in the biological sciences and related fields, there is a Biology Living Learning Community.

  • Pre-health Professional programs are available for students interested in health careers
  • Numerous internship and summer program options
  • Hands-on research opportunities with faculty mentors
  • Four registered student organizations
  • Outreach programs that service the surrounding community
  • Classrooms and laboratories stocked with state-of-the-art equipment

The mission of the Department of Biological Sciences is to help our students achieve their academic, career and personal goals. To accomplish this, the faculty of the department provide students with a fundamental understanding of basic and modern biological principles, critical-thinking skills and opportunities for enrichment through regular one-on-one advising, career guidance and research experience. A distinguishing aspect of the training offered by the department is that it is attained within the context of the Marianist and liberal arts traditions.

As part of these traditions, the Biology curriculum, in conjunction with the core curriculum of St. Mary’s University, seeks to develop our students into responsible citizens capable of solving problems that will help society.
