Simon Gray, MD, PhD

Gastroenterology Fellow

Simon Gray was born in South Africa and grew up in Maryland. He studied Chemical Engineering as an undergraduate at the University of Maryland, Baltimore County and as a Gates-Cambridge Scholar at the University of Cambridge, where his research focused on cell separation technologies. Simon earned his MD/PhD at the Yale School of Medicine in the Department of Immunobiology. His PhD thesis was completed under the mentorship of Dr. Susan Kaech and focused on the epigenetic regulation of CD8+ T cell development. Simon’s clinical interest is inflammatory bowel disease and he plans to pursue research studying the intersection of the gut microbiome and mucosal immunology in the gastrointestinal tract and liver. He hopes to blend his engineering and bioinformatics backgrounds with expertise in basic wet-bench research to further understanding of and develop therapies for inflammatory bowel disease.
