An interview with Jayaraj Rajagopal.

Jayaraj (Jay) Rajagopal is a Principal Investigator at the Center for Regenerative Medicine at Massachusetts General Hospital and an Associate Professor of Medicine at Harvard Medical School. A Howard Hughes Medical Institute Faculty Scholar, his lab works on the development and regeneration of the lung. He uses stem cell and animal models to develop novel insights that hopefully will provide inspiration for therapies to help treat human lung disease. He was awarded the Dr Susan Lim Award for Outstanding Young Investigator at the 2017 International Society for Stem Cell Research (ISSCR) meeting in Boston (MA,USA), where we met him to talk about how a fish tank started a life-long fascination with the lung, the transition to running his own lab, and his optimism for the future of both basic stem cell research and its clinical translation.
