Harvard Medical School has created a large department dedicated to developing and teaching young scientists about the emerging field of computational medicine. This field uses new mathematical techniques to make sense of the thousands of numbers generated in experiments measuring various molecules. Analyzing such "big data" was once unimaginable. Now, scientists have the tools to do it, and to compare tissue of people with and without a disease to find out which molecules are different.
