John P. Leonard, M.D.
Interim Chair, Weill Department of Medicine

As the Interim Chair of the Weill Department of Medicine, I look forward to the extraordinary journey ahead with the utmost enthusiasm. We are indebted to those pioneering physicians and scientists who drove the major discoveries over the past century, but we cannot rest on their laurels. Today's world of translational research offers undiscovered vistas to explore that will open the door to life-saving therapies. An ever-expanding universe of biomedical sciences, genomics, and technological tools will provide the key.

New York City offers an ideal setting for our pursuits, a multicultural academic mecca providing a full spectrum of patient cohorts and diseases that is unparalleled anywhere in the world. Our researchers are collaborating on projects nationally and internationally with colleagues at the Clinical and Translational Science Center (CTSC) here at Weill Cornell Medicine/NewYork-Presbyterian, as well as with our neighboring world-class institutions, Memorial Sloan-Kettering Cancer Center, Rockefeller University, and Hospital for Special Surgery.
