Dr. Forger is a neuroscientist with special interests in hormones, development, and sexual differentiation of the nervous system. Current research projects in the lab examine how cell death and epigenetics contribute to sex difference in the brain. She was a Professor at the University of Massachusetts – Amherst for 18 years before joining GSU in 2012. Career research highlights include the first identification of a sex difference in the human spinal cord, some of the earliest work on neurotrophic factors and sexual differentiation, the role of cell death genes in the development of sex differences and, most recently, the role of epigenetics in sexual differentiation of the brain. In addition to work on more traditional lab animals (rats and mice), she has also been Principal Investigator on a project examining the effects of sex and social status on the brains of naked mole-rats, and was a long-time collaborator on the Berkeley spotted hyena project. Her research has been supported by the National Institutes of Health, the National Science Foundation, and the Whitehall Foundation. She has been the recipient of two NIH Independent Scientist Awards and the Samuel F. Conti Award for Research Excellence from the University of Massachusetts. She has served on study sections for the National Institutes of Health and National Science Foundation, and currently serves on the Editorial Boards of the journals Endocrinology and Hormones and Behavior. She is a Councilor of the Organization for the Study of Sex Differences, and a member of the Executive Board of the Society for Behavioral Neuroendocrinology.
