Biology BS

College of Sciences / Natural Sciences
Undergraduate major / Bachelor of Science

About The Program

Biology is the study of life, from the simplest cells to the most complex ecosystems. When you study biology you develop an understanding of your own life and an appreciation for your connection to the natural world. A Bachelor of Science in Biology degree helps open the door to a range of career fields including health care, food science, public health, biotechnology, conservation and natural resource management.

The BS in Biology offers students a comprehensive introduction to the biological sciences with a strong foundation in mathematics and the physical sciences, followed by advanced study in at least one area of student interest.

BS in Biology graduates may choose to continue on to professional and graduate programs in health care, research and education. The biology major provides students with scientific knowledge, laboratory skills, research experience and intellectual training in analytical and quantitative reasoning. Possible career titles with a bachelor’s degree in biology include Biochemist, Biological Technician, Environmental Scientist, Health Services Manager, Pharmaceutical Sales, and Food Scientist. A Biology BS major, plus a Health, Humanities, and Community minor is a recommended pathway for students considering careers in professional healthcare programs (medical school, dental school, pharmacy, physician’s assistant programs, veterinary school). Biology BS graduates are well positioned for laboratory jobs in life sciences companies and government laboratories around the Twin Cities. Biology BS majors may consider going to graduate school in life sciences programs for a master's or PhD degree.
