All PhD students at Indiana University School of Medicine must select a minor. The requirement provides additional breadth and depth to the graduate curriculum. The minor consists of courses outside of the major department and may be in one of the other basic medical science departments or from one of a number of interdisciplinary minors, including diabetes, cancer, cardiovascular sciences and bioinformatics. Most minors require 12 credit hours of course work. In cases where less than 12 credit hours are required, students take additional elective courses from the department of focus.
