Microbiology, Bachelor of Science

Ever since Van Leeuwenhoek described the “cavorting wee beasties” seen through his simple 1670s-style microscope, scientists have been fascinated by tiny life forms. This degree allows students to join those who explore the world of bacteria, viruses, mitochondria, neurons, and genetic material. A strong core of biology and chemistry anchors the program, which offers flexibility through a generous selection of approved electives.


What Can I Do with a Bachelor of Science in Microbiology?

Are you interested in infectious disease? Do you want to help conduct clinical trials for new drugs? Microbiology might be the career path for you. You can also use our program to prepare for graduate study, for admission to medical, dental, or veterinary school, or for other professional training.

You'll receive plenty of personal attention from faculty-in the classroom, in research laboratories, and in our Biology Advisement Center. You'll have numerous opportunities, even as an undergraduate, to do research-research that might get you a job in a lab or get you into medical school. Our graduates have exceptional placement rates in medical schools, government agencies, and graduate programs.

Career opportunities that might be pursued:
  • Medical corporations
  • Biological testing laboratories
  • Pharmaceutical companies
  • State or federal government agencies

With further education, one of these paths is possible:
  • Physician
  • Researcher
  • Crime lab analyst
  • University professor
