Biology is a dynamic science that helps you gain a better understanding of living organisms and the ways they interact with our environment. SLU’s biology program provides a foundation for careers in medicine and the life sciences, as well as post-graduate studies. 


Major in Biology

Saint Louis University's Department of Biology offers both a Bachelor of Arts and a Bachelor of Science degree . The Bachelor of Arts degree in biology provides flexibility in selecting upper-level courses and is favored by students interested in double majors. The Bachelor of Science degree in biology allows you to choose from five concentrations of study to focus on specific sub-disciplinary areas:

Biological Science
This concentration provides students with a strong foundation in biology and prepares you for entry-level employment in the life sciences, health professions, K-12 education and graduate school.

Biological Chemistry and Molecular Biology
This concentration focuses on the latest advances in biochemistry, genomics, and molecular and cell biology. It is designed for students interested in careers involving biomedical research or biotechnology.

Cell Biology and Physiology
This concentration provides students with a strong foundation in the structure and function of organ systems and the tissues that comprise them. It is a good choice for students planning careers in medicine, pharmacology or health care.

Ecology, Evolution and Conservation 
This concentration is designed for students interested in various aspects of organismal biology. It is a good choice for students preparing for graduate study or planning for a career as a research biologist or wildlife specialist.

Plant Science
This concentration is designed for students interested in various aspects of plant biology and prepares you for careers in agricultural industries, botanical research institutes and advanced training in graduate degree programs.

Biology majors at SLU can enroll in courses that provide credit for structured internships through collaborations with a variety of local organizations including the Missouri Botanical Garden, Saint Louis Zoo, Sigma Aldrich, Monsanto and firms in the growing biotechnology field.

SLU's Department of Biology also has a field station located in the Missouri Ozarks for research and teaching that provides unique opportunities for you to explore ecology and conservation biology through hands-on experiments and undergraduate research.

Highlighted Courses
  • BIOL 1040-1060: Principles of Biology I and II
  • BIOL 1150: Genetics and Human Diversity

Internships and Careers

Advanced undergraduate students with good academic records are encouraged to apply for positions as teaching or learning assistants. In addition to a stipend, students gain teaching experience and the opportunity to help others become interested in the field of biology.

SLU’s biology major develops strong critical thinking and problem solving skills that provide an excellent preparation for professional schools, such as:

  • Medical school
  • Veterinary science
  • Dental school
  • Optometry school

The skills you gain as a biology major can also open the door to a wide variety of career options in areas such as health care, biotechnology, environmental management, conservation, education and pharmaceuticals.


Our faculty — all of whom hold the highest degrees in their field — are active in research. Funded by grants from federal and local agencies, they conduct studies in diverse subdisciplines within biology, including molecular biology, cell biology, and ecology and evolutionary biology. They also provide courses that engage and challenge students by promoting active learning.
