I'm definitely interested in getting an MPH, but I am serious enough about the research side that I think a PhD would be more appropriate. (Of course, that depends on whether or not I can get into a program. There seem to be so few places that will support an MD/PhD in something other than the traditional biomedical sciences. In fact, the majority of my apps were to regular MD programs at schools with strong PH schools, not MD/PhD programs.)
Also, though this sounds strange, one of the reasons I applied MD/PhD to UNC is because I consider myself to be a stronger applicant as MD/PhD... I have a lot of research experience, but very little clinical/volunteer experience... I honestly don't know if I would have gotten a secondary as a regular MD applicant!
Just out of curiosity, do you know if it is a big deal to receive a secondary from UNC's MD/PhD program? I'm trying to assess the strength of my app after getting my first MD/PhD rejection yesterday...
