Microbiology Undergraduate Major (BS, HBS)
This major offers the following option(s):
Administered by the Department of Microbiology under the School of Life Sciences in the College of Science.
The undergraduate BS degree in Microbiology (MB) provides broad training and opportunities to specialize in health, environmental, computational or biotechnological microbiology. Graduates with BS degrees frequently enroll in professional programs, such as medical, dental, and pharmacy programs, or are hired as microbiologists by the biomedical, food, beverage or biotechnology industries. This program offers hands-on training in microbiology laboratory courses and advanced opportunities for undergraduate laboratory and field research experiences.
Students may elect to complete one transcript-visible option in Pre-Medicine or Aquatic Microbiology, although an option is not required.

- Apply specialized microbiology knowledge from multiple fields to critically analyze and evaluate microbiological, environmental, and health-related problems.
- Demonstrate competency in routine and specialized microbiological laboratory skills applicable to microbiological research or clinical methods, including laboratory safety and accurately reporting observations and analysis.
- Communicate scientific concepts, experimental results and analytical arguments clearly and concisely, both verbally and in writing.
- Practice flexible professional skills needed for careers in microbiology and related scientific and professional fields.
Students majoring in Microbiology cannot seek a dual degree or double major in Biochemistry & Biophysics, Biochemistry & Molecular Biology, BioHealth Sciences, Biology or Zoology.
To receive the BS degree in Microbiology, a student must complete all university baccalaureate core requirements plus departmental requirements listed below. All departmental requirements must be taken for a grade, with the exception of CH 324, which may be taken S/U; however, if taken S/U the student will not receive the Chemistry minor.
MB majors must complete the following courses with a grade of C- or better: MTH 227 or MTH 251, CH 231, CH 232, CH 233, CH 261, CH 262, CH 263 and CH 331.
MB majors must have a minimum 2.0 GPA in microbiology classes. This includes courses in the Microbiology Sciences Core, Microbiology Laboratory, and Microbiology Electives.
MB majors planning advanced professional training in medicine, dentistry, pharmacy, etc, should consult an appropriate advisor.
