I'm an MD/PhD student, and after a lot of shadowing and considering all of my options, I've decided I want to become an EM physician. I have not started the PhD portion of my program yet (the lab I plan to join does immunology research.) This is unfortunate, as I know the field of EM will make it especially difficult to establish a career with a basic science research component. My clinical interests just don't seem to match up with my research interests. What I'm wondering is if residency program directors will question my motives/judgement with a PhD in immunology. Most MD/PhDs go into IM, path, peds, neuro, etc. Having a background in basic science research can't HURT my residency prospects, can it?
