<p>So I was wondering what the best course of action would be to become an epidemiologist. Would an MD/MPH be the best path to go (i.e. open up more career opportunities), or a PhD in Epidemiology? Another question: If I were to go immediately from undergrad to a Master's or PhD, which undergrad would be best looked upon by epi schools? Something like a Math or Bio major with the other being a minor?</p>
