Some people might think that it is unusual that my research group accepts students from diverse academic training backgrounds like epidemiology, mathematics, statistics, computer science or biology. However, I feel very strongly that this diversity enhances the ability of our research group to address important infectious disease questions by allowing students to interact across traditional disciplines. This interaction enriches the research experience of students here in my research program. This month in The Scientist magazine there is an article which describes the "next step" that some universities are taking in this regard by offering truly interdisciplinary advanced degree programs.
