Quantitative Ocular Genomics Laboratory
Xiaoyi “Raymond” Gao, PhD, Director
Associate Professor of Ophthalmology
Research Interest: Vision disorders, human genetics, statistical genomics, and bioinformatics.
Ongoing Research: Current investigations include the Mexican American Glaucoma Genetic Study (MAGGS), which aims at identifying genetic determinants related to open angle glaucoma in Mexican Americans, and investigations into the genetics of diabetic retinopathy and age-related macular degeneration in admixed and minority populations.
Impact: Discoveries in ocular genomics will extend our understanding of eye diseases/traits by identifying relevant genetic variants, genes and pathways, thereby potentially leading to early detection and effective treatment of many eye disorders which can lead to blindness.
