Microbiology Major (B.S.)

Microbiology is the study of microscopic organisms, including bacteria, viruses, fungi, algae, and parasites. The Microbiology Major B.S. provides the knowledge base and lab experience to prepare for a variety of careers in areas of biotechnology, human health (e.g., immunology, vaccines, antimicrobials, pharmaceuticals, food and water quality control), as well as microbial diversity and ecology.

Students in this program are encouraged to participate in research opportunities and clinical observation during their junior and senior years to prepare for a successful career in research and/or development.

Careers with a Microbiology Degree

Microbiology graduates are prepared for jobs in biotechnology and health industries, as well as further graduate studies in medicine, dentistry, optometry, public health, microbiology, or molecular biology.

With our increased understanding of the importance of both positive and negative effects of the microbiome on human health and the environment, career opportunities and outlook are very good.

Admission Requirements

In the past, Biological Sciences had a very strong admission requirement of a PL1-level math placement. With the implementation of the test optional admission pathway, this requirement is no longer in place. However, achievement of PL1-level math placement can be a good indicator of strong preparation in math. After admission to Ohio University, first-year students may transfer into a Biological Sciences major if they have earned a grade of “C” or better in both BIOS 1700 and BIOS 1705 and have a minimum accumulative GPA of 2.5 at Ohio University.

For information about changing your major to biological sciences or transfer admissions requirements, view the academic catalog.

Student Success Stories

Jayanna Smith: From Small Town to Prestigious Award

Jayanna Smith won a 2024 Goldwater Scholarship, the nation's most prestigious award for undergraduate STEM students. “It means a lot because I come from a really small town,” Smith says. “Coming to a larger school, I initially found it hard to feel like I belonged here. I struggled with imposter syndrome. Winning the Goldwater gave me confidence," Smith says. "I was so scared that I would never figure out a career path. I would tell my younger self to relax and enjoy it a bit while also working hard.

Ben Stiadle Wins Prestigious Award for Diabetes Research

Molecular Biology student Ben Stiadle won a 2024 Goldwater Scholarship, the nation's most prestigious award for undergraduate STEM students. His research investigates treatments for Type 2 diabetes. He uses a florescent probeto track the amount of calcium in the beta cell in real time in order to better understand the role of the sodium-potassium ATPase (NKA), an ion exchanger in cells. Stiadle works with Dr. Craig Nunemaker to further his interest and understanding of the treatment process for chronic diseases.
