I am currently researching PhD programs to apply to in the Fall. I have an MPH in Epidemiology already and currently working as a researcher. I'm fairly new to research, so I was wondering are there any programs out there that features research rotations in different fields? I was thinking about applying to PhD programs in Epidemiology, which I will apply to a few. But after meeting with my mentors, a program with research rotations would be more beneficial for me. UMass Medical has a PhD program in Clinical and Population Health (http://www.umassmed.edu/cphr/academics/rotations.aspx) that features this. So I am wondering does anyone know of any similar programs?
