John M. Greally

John M. Greally, DMed, PhD, MB, BCh, BAO, is Chief of the Division of Genomics in the Department of Genetics, Director of the Center for Epigenomics and Professor of Genetics and Pediatrics at Montefiore Einstein. Dr. Greally is a specialist in clinical genetics, with an emphasis on rare diseases and congenital conditions. He has expertise in medical genomics, the use of advanced genomic technologies to diagnose genetic conditions.

Dr. Greally obtained his Bachelor’s degree in Medicine, Surgery and Obstetrics in 1988 from the National University of Ireland in Galway, Ireland. He received his Doctorate of Philosophy in 1999 and his Doctorate of Medicine in 2016 from the same institution.

Basándose en su enfoque clínico, el Dr. Greally dirige un programa de investigación que utiliza tecnologías genómicas, técnicas avanzadas de análisis de datos y sistemas de células madre para comprender los mecanismos de las enfermedades genéticas humanas, con especial atención a las variantes raras de la secuencia de ADN en la mayoría no codificante del genoma humano. Su objetivo es mejorar nuestra capacidad para diagnosticar enfermedades raras y la prestación equitativa de servicios genómicos a poblaciones de todos los orígenes. También ha iniciado una empresa emergente, Latent Genomics, para permitir el uso eficaz de la genómica médica en la atención clínica.

Dr. Greally holds a United States Patent titled Methods for determining cytosine methylation in DNA and uses thereof. His work has been published in numerous peer-reviewed journals, chapters and books, and he has presented nationally and internationally. He sits on the editorial board of Epigenetics and Chromatin (BioMed Central) and is a section editor for Epigenetics at PLOS Genetics.

Dr. Greally is board certified in pediatrics by the American Board of Pediatrics and in clinical genetics and genomics by the American Board of Medical Genetics. He is a member of the American Society of Human Genetics and a fellow of the American College of Medical Genetics and Genomics. Dr. Greally has been appointed president of the New York Celtic Medical Society from 2021 to 2023, and in 2014 he won Mentor of the Year in Basic Science from Montefiore Einstein.
