Hello, I'm a medical doctor in Japan and applied for some public health school programs in the U.S. One of them, Harvard MPH program, accepted me. I'd like to know more about Harvard School of Public Health(HSPH). My question is whether HSPH MPH program is enough for the preparation to work in the field of public health. The reason whty I wondered like this is that HSPH offers only 9 months to study. It's the shortest program as far as I know. To learn more, HSPH thinks that I should continue to pursue Ph.D. or DrPH ? Will schools offering two years MPH program give me much deeper understading or more practical experience in this field? Not for academic interest but for work , should I choose two years MPH program? (At now, I was also accepted by Emory SPH Epidemiology. I'm wondering which to choose. ) Thanks in advance. P.S. My interest is epidemiology especially related to chronic diseases like diabetes. I'm interested in not only genetic factors but environmental factors.
