Dr. Bobby Cherayil


Dr. Bobby Cherayil is a graduate of Christian Medical College, Vellore, India, where he received the MBBS degree followed by an MD in pediatrics. He did post-doctoral training in immunology at the Whitehead Institute for Biomedical Research and at the Massachusetts General Hospital. He is currently an Associate Professor of Pediatrics at Harvard Medical School and directs a laboratory that studies innate immune responses to bacterial enteropathogens. In addition to his laboratory research, he is actively involved in teaching cellular and molecular immunology to medical and graduate students, and holds positions on a number of grant review and editorial committees, including as a Section Editor of the Journal of Immunology.
