Krishnan Raghunathan, PhD

  • Research Assistant Professor of Pediatrics

Krishnan Raghunathan, PhD, is a membrane biophysicist by training and his interests lie in understanding how the diversity in composition affects membrane organization and function. In the laboratory of Terence Dermody, MD, he is studying these aspects of membrane biology in the context of virus-host interactions. In particular, he uses microscopy and lipidomic tools to understand physicochemical aspects of how chikungunya virus remodels the membrane. He is further interested in the functional consequence of these changes from the perspectives of both the host and the virus, and their extension to other alphaviruses.
