Dr. Cheryl Lyn Walker is the Director of the Center for Precision Environmental Health at Baylor College of Medicine, where she holds the Alkek Presidential Chair in Environmental Health and is a Professor in the Departments of Molecular & Cell Biology and Medicine. Dr. Walker is an international leader in environmental health, and  elucidating molecular mechanisms of disease.  Her studies on the role of the epigenome in gene-environment interactions have yielded signifiant insights into mechanisms by which early life exposures influence health and disease across the lifecourse.  Her work has also led to the discovery of a dual role for the cell’s epigenetic machinery in remodeling both chromatin and the cytoskeleton.
