Current Lab Member Profiles:

Jayakrishna Ambati, M.D.  Principal Investigator

Dr. Jayakrishna AmbatiJayakrishna Ambati is Professor of Physiology and Professor & Vice-Chair of Ophthalmology and Visual Sciences at the University of Kentucky. He holds the Dr. E. Vernon Smith & Eloise C. Smith Endowed Chair in Macular Degeneration Research. His scientific aspirations are to identify the molecular mechanisms underlying the development of AMD, determine the triggers of the angiogenic switch that converts this disease from an atrophic to a neovascular phenotype, and to develop novel therapeutics to prevent and treat this blinding condition. He is the first ophthalmologist to win the Doris Duke Distinguished Clinical Scientist Award and a Burroughs Wellcome Fund Clinical Scientist Award in Translational Research. He was also elected to The American Society for Clinical Investigation and was the first ophthalmologist to be elected to The Association of American Physicians. He has been elected as a Fellow of the American Association for the Advancement of Science. He also serves on the Editorial Board of Investigative Ophthalmology & Visual Sciences and is an Associate Editor of Ophthalmology. He won the 2010 ARVO Cogan Award, and his Cogan Lecture was recognized with the 2010 Cless Best of the Best Award. He also won the 2010 Roger H. Johnson Memorial Award for Macular Degeneration Research, and a 2010 Research to Prevent Blindness Senior Scientific Investigator Award. He has been named winner of the 2011 AFER/Pfizer Ophthalmics/Carl Camras Translational Research Award.
