I am a professor of biomedical informatics at Harvard Medical School and director of the PhD program in Bioinformatics and Integrative Genomics. My group (http://compbio.hms.harvard.edu) specializes in computational analysis of DNA sequencing data in epigenetics and cancer genetics. As an undergraduate (Winthrop House ’94) and graduate student (Caltech), I studied applied math and tried to stay as far away from the biological sciences as possible. But soon afterwards, I discovered that there are many fun math problems in genomics with immediate relevance to medicine and biology, and I have not had to look for a job since then. While in college, I played in the Harvard band, rowed intramural crew, and was active in Christian Fellowship.
