D.O./Ph.D. in Biomedical Sciences Dual Degree

The Doctor of Osteopathic Medicine and Doctor of Philosophy in Biomedical Sciences (D.O./Ph.D.) program is offered to medical students interested in medical research and/or academic medicine. This degree is designed for the future physician who desires to see patients in a clinical setting while still maintaining an active interest in research.


Areas of emphasis include biochemistry, cell biology, microbiology, pathology, pharmacology and physiology.

Program Sequence

The D.O./Ph.D. program is typically completed in seven years. All degree requirements must be completed within nine years of entering the dual degree program.


# Years Links
Year 1-2 Complete first and second year medical school curriculum (D.O)
Year 3-5 Complete Ph.D. degree requirements including courses, comprehensive qualifying examination, research, dissertation, (approximately three years)
Year 6-7 Complete third and fourth year medical school curriculum (D.O)

A total of 60 graduate credit hours are required for the Ph.D. degree; with a minimum of 30 hours course work and 30 hours of Research and Dissertation. D.O./Ph.D. students receive 30 hours of graduate credit for the medical school courses taken in the first two years of the medical school curriculum. D.O./Ph.D. students are typically not allowed to transfer graduate credit from other institutions.


The requirements for the Ph.D. degree component of the D.O./Ph.D. degree are similar. However, there are some requirements that are unique to the D.O./Ph.D. degree program.


During the first and second year of medical school, D.O./Ph.D. students are required to take Medical Biochemistry and two other medical school courses of their choosing, for graduate credit (i.e., students must sign up for the BIOM section of the course). The courses taken in the first two years account for 30 semester hours of graduate credit toward the Ph.D. degree. An additional 30 semester hours of graduate course work must be completed by taking both required and elective courses. D.O./Ph.D. students may take up to nine hours of special topics and four hours of seminar.


Application Process for the D.O./Ph.D. Degree

In addition to submitting the biomedical Ph.D graduate application materials listed in the Biomedical Ph.D., dual degree students must apply separately to the D.O. program. The student must submit an AACOMAS application online by February 28 their year matriculation and pay the AACOMAS application fee.


Please consult the D.O. admissions webpage for a complete list of application materials and procedures. D.O./Ph.D. students may apply upon acceptance to medical school or within their first two years of medical coursework.


Application Requirements Specific to the D.O./Ph.D. Program

Transfer Credits

D.O./Ph.D. students are typically not allowed to transfer graduate credit from other institutions. Under specific circumstances, additional transfer credit may be approved by the advisory committee. Transfer credit must comply with the transfer guidelines as stated for the Ph.D. program. Required courses must be taken at the OSU Center for Health Sciences.



Students are required to maintain a GPA of 3.0 or better in their biomedical coursework. An academic review will occur in May at the end of each year of coursework to evaluate the progress of the student in the program. The D.O./Ph.D. student is required to enter the Ph.D. portion of the program after completing the first 2 years of the medical curriculum.


All other coursework, credit hours, research proposal, and qualifying examination requirements are the same as outlined in the Ph.D. program requirements and restrictions.
