Stephen H. Tsang MD, PhD has been culturing embryonic stem (ES) cells since 1992 and in 1995 created the first mouse model for a recessive form of retinitis pigmentosa (RP) by applying homologous recombination to ES cell technology. Since 1996, the Dr. Tsang has been quantifying retinal function and structure in gene-targeted mutant mice. As the director an international referral center for inherited retinal degenerations, Dr. Tsang cares for a specific subgroup of patients that are most appropriately aligned with precision medicine. At times, patients suffer from a disorder that is related to an existing transgenic mouse model generated in the laboratory, and other times patients inspire new models. . Dr. Tsang's contributions to genetics has being recognized by the 2005 "Bernard Becker-Association of University Professor in Ophthalmology"-"Research to Prevent Blindness" Award, Carl Camras Award, and the 2013 Bradley Straatsma Lectureship. Dr. Tsang received 2008 resident teaching award. He is also a standing member of the "DPVS" study section at NIH, American Society for Clinical Investigation, American Ophthalmological Society and Macular Society.
