David is an MD-PhD student at Harvard Medical School in the Harvard-MIT Health Sciences and Technology program. He received his A.B. in Chemical and Physical Biology from Harvard College. As an undergraduate, David worked in Peter Turnbaugh’s lab at the FAS Center for Systems Biology studying the interactions between diet, xenobiotics, and the gut microbiota. After graduating, he continued working in the Turnbaugh lab for a year and is proud to note that he is a “published poop researcher.” If you ask him, he will assure you that it is just as glamorous as it sounds. David joined the Kwon Lab in January 2014 and is interested in the interaction between the immune system, gut epithelium, and gut microbial community, and how this relationship changes during HIV infection and across different geographic locations.
