<p>OP you may want to consider studying Epidemiology as a major. Rochester is one of the few schools in the country that has an epidemiology program for undergraduates. The program is through the publice health program. You can also be pre-med and study epi. My daughter is a senior ar Rochester, she is pre-med and she is an epi major. She also will probably be staying for a fifth year to get her MPH. She has been able to do research and is doing neonatology research at NYU hospital this summer. Her epi background is what landed her the internship. Like you she is unsure where her ultimate career will lead her but she is leaving open the option of either getting her MD or Phd. Also if you wanted to pursue epi as a Phd, the top programs are at Harvard, Emory and North Carolina.</p>
