Dr. Rajagopal is a developmental biologist at the Harvard Stem Cell Institute and a pulmonologist at the Massachusetts General Hospital. His research interests include lung developmental and regenerative biology and the application of developmental biology to human disease. His current focus is the identification of a lung stem cell. Using an efficient in vivo model of tracheal regeneration, he has developed a novel functional assay for lung stem cells. His research program also includes projects to differentiate human embryonic stem cells into lung cells and projects that involve the use of large screening platforms to isolate and identify self-renewing lung stem cells in culture.

Researchers in the Center for Regenerative Medicine at Massachusetts General Hospital and the Harvard Stem Cell Institute have taken a critical step toward a treatment for Cystic fibrosis and other fatal lung diseases.
MGH researchers have taken a critical step in making possible the discovery in the relatively near future of a drug to control cystic fibrosis, a fatal lung disease that claims about 500 lives each year, with 1,000 new cases diagnosed annually.
