How Old is That Polar Bear? The Answer is In Its Blood
The New York Times - August 10, 2023
John Greally, M.D., Ph.D., D.Med., says he remains skeptical about the value of so-called epigenetic clocks, which estimate an organism's age by analyzing chemical tags on its DNA. Dr. Greally is director of the Center for Epigenomics, professor of genetics and of pediatrics, and chief of the division of genomics at Einstein, and a pediatric geneticist at Children’s Hospital at Montefiore.
Can We Really Inherit Trauma?
The New York Times - December 19, 2018
John Greally, D.Med., Ph.D., says the reported conclusions of animal studies suggesting that trauma can be passed down to future generations through epigenetic changes are overstated. Dr. Greally is director of the Center for Epigenomics and professor and chief of computational genetics at Einstein and a clinical geneticist at Children’s Hospital at Montefiore.
Nature interviews John Greally, M.B.B.Ch., Ph.D., about his criticism of a recent New Yorker article on epigenetics. Dr. Greally is professor of genetics, of medicine and of pediatrics and the director of the center for epigenomics at Einstein and attending physician at the Children’s Hospital at Montefiore.

The New York Times interviews John Greally, M.B.B.S., Ph.D., about a new study that suggests a father’s experiences may influence the biology of his offspring. Dr. Greally notes the study size was small and therefore not conclusive. However, he suggests that research involving hundreds of subjects may help pin down whether epigenomic factors, namely molecules that turn genes on and off, can be passed down to children. Dr. Greally is professor of genetics, of medicine and of pediatrics and the director of the center for epigenomics at Einstein and attending physician at the Children’s Hospital at Montefiore.

The New York Times features John Greally, M.B.B.Ch., Ph.D., and the artist who works with Einstein’s genetic researchers to help visualize “big data.” Dr. Greally explains that large biological data sets are relegated to the digital realm and it is difficult for researchers to develop an instinct for what’s important. Dr. Greally is professor of genetics, of medicine and of pediatrics and director of the center for epigenomics at Einstein and attending physician at the Children’s Hospital at Montefiore.

New York Daily News interviews John Greally, M.B., B.Ch., Ph.D., about his study that found environmental influences may play a role in the development of autism. Dr. Greally identified epigenetic changes, which can control which genes are turned on or off, that may be implicated. Dr. Greally is professor of genetics, of medicine and of pediatrics, director of the Center for Epigenomics and the Ruth L. and David S. Gottesman Faculty Scholar for Epigenomics at Einstein and attending physician, pediatrics at The Children's Hospital at Montefiore.

Nature.com features comments by John Greally, M.B., B.Ch., Ph.D, about the Roadmap Epigenomics Project and its effort to identify and map all the chemical tags, known collectively as the human epigenome, that control the activities of genes. Dr. Greally notes that although having the complete mapping information is valuable overall, the data may be tricky to utilize for most researchers when studying specific diseases. Dr. Greally is an associate professor of genetics and of medicine and the Faculty Scholar for Epigenomics.
