Molecular and Cellular Biology graduate and MSTP student, Mario Pineda always intended to become a physician for underserved populations.  While pursuing this goal as an undergrad, he became engaged in HIV/AID research. He learned about the Medical Science Training Program (MSTP) offered through MCB, that would allow him to get a PhD in biomedical sciences and complete his training as an M.D. Mario describes the flexibility of the MCB Program as the lure that attracted him to this doctoral program, but the hook was his ability to use an Antarctic teaching experience as one of his TA requirements.
