John M. Greally, M.B.,B.Ch., Ph.D.

Chief, Division of Computational Genetics, Einstein

Director, Center for Epigenomics, Einstein

The Ruth L. and David S. Gottesman Faculty Scholar for Epigenomics, Einstein

Attending Physician, Pediatrics, The Children's Hospital at Montefiore


Dr. Greally began his career as a pediatrician who subspecialized in clinical genetics, seeing patients with genetic syndromes, birth defects and developmental problems. Now, Dr. Greally seeks to understand how genetic disease is caused not by DNA mutations, but due to abnormalities in how genes are switched off and on – a field known as epigenomics. 

Dr. Greally’s research focuses on epigenetic abnormalities in human diseases such as breast cancer, type 2 diabetes, viral hepatitis, and allergies and on epigenetic regulation of stem cell differentiation. He also serves on the editorial board of the new journal Epigenetics and Chromatin
