Biological Sciences Major (B.S.)

The flexible Bachelor of Science degree in Biological Sciences is particularly well-suited for students who plan to enter a biological sciences graduate program or professional school. Biology courses can be chosen to prepare for a specific area of interest while fulfilling the biology breadth requirement.

This major fulfills the needs of students interested in specializations in clinical laboratory science/medical technology, exercise physiology, or neuroscience. With careful selection of elective courses, this track also meets the pre-requisites for applying to medical, physician assistant, dental, optometry, and veterinary programs.

Careers with a Biology Degree

Students who earn a Biological Sciences degree are prepared for a wide range of careers, including work in the state and federal government, higher education settings, the health industry, research laboratories, environmental organizations, Centers for Disease Control and Prevention, nature centers, museums, and more. This track is particularly well suited for students who plan to enter a biological sciences graduate program or professional school.

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.
