MSUCOM has a DO/Ph.D program. The info about it is on their website. (www.msu.edu, then click on grad programs, and it should have a link on the med school page) I'm pretty sure that you have to apply for the program with your secondary. If I remember correctly from last year, they send a huge secondary packet, and the application is with the packet. They don't send secondaries to everyone (not even all MI residents). Correct me if I'm wrong about how to apply to their DO/Ph.D program.
