The 2015 Nobel Prize in Chemistry was awarded to Tomas Lindahl, Paul Modrich (Former Damon Runyon Fellowship Sponsor) and Aziz Sancar (Former Damon Runyon Fellowship Sponsor) “for having mapped, at a molecular level, how cells repair damaged DNA and safeguard the genetic information. Their work has provided fundamental knowledge of how a living cell functions and is, for instance, used for the development of new cancer treatments.” We congratulate two Damon Runyon alumni, Robert S. Lahue, PhD (Damon Runyon Fellow ‘85-‘88 in the Modrich lab) and David Mu, PhD (Damon Runyon Fellow ‘94-‘97 in the Sancar lab), who each made seminal contributions to the body of scientific knowledge that resulted in this year’s Nobel Prize.
