I am currently an undergrad student studying biology and I am trying to figure out what my next step will be. I am interested in epidemiology and thats the route I want to go, but I want more clarification on the MPH and PhD differences. Primarily career duties. Is one more hands on than the other? Is one more in demand? Is there a significant difference in job outlook? Any info and descriptions would be helpful! From research I've done online I seem to be more interested in the field aspect. Like traveling, observing, hands on research, etc. Would one of these be better for this? Thanks!
