In 1996 he became a member of the U.S. National Academy of Sciences. His research discoveries included finding compelling evidence for the recessive nature of oncogenic mutations at tumor suppressor genes like the retinoblastoma gene, the identification and cloning of the retinoblastoma gene, and the identification of 16 different genes responsible for retinitis pigmentosa and other forms of retinal degeneration and retinal dysfunction. In 2006 Dr. Dryja joined the Novartis Institutes for Biomedical Research where he was the Global Head of Translational Medicine in Ophthalmology (2006-2009) and then the Vice President and Global Head of Ophthalmology research (2009-2017).
