Don't know too many details, but I have also heard that it is one of the best MPH programs out there. I am also pretty sure that getting your MPH does not cost you anything extra if you are an MD student, and both MD/MPH can be done in 4 years if you take summer classes. Tulane has International and Tropical Med. degrees through their School of Public Health...I have not heard of any other schools that have such programs.
