At the time he saw the Cosmos episode, Eswarappa was a postdoctoral fellow in cell biology at the Cleveland Clinic studying cancer and other pathologies associated with the abnormal growth of blood vessels. About a year later, in 2015, he was tapped to launch his own group at the Indian Institute of Science in Bangalore, and he recruited graduate ...
