Ph.D. Admissions Requirements and Application Process

For entry into the Ph.D. program starting Fall 2025, the deadline for receipt of a completed application (including letters of reference, any exam scores, and transcripts) is January 1, 2025.

We welcome applications from a variety of science and engineering majors. Successful students have entered the program with Bachelors degrees in Chemistry, Biochemistry, Biology, Molecular Biology, Psychology, Neuroscience, Chemical Engineering, Computer Engineering, Marine Biology, Microbiology, and pre-medical and pre-health sciences degrees, among others.

We utilize a holistic application review that takes into account multiple factors, including field of interest, when making admissions decisions.

Our program is unable to provide application fee waivers. Domestic applicants can apply for a waiver through the OSU Graduate School. International applicants can check with their local EducationUSA advising office to see if there are educational opportunity programs or local recommendations to fund study in the United States.

Applicants with a foreign BPharm degree without research experience are generally not competitive for this program.
