Biosketch

Dr. Tracy Bale is a Professor of Pharmacology at the University of Maryland School of Medicine and Director of the Center for Epigenetic Research in Child Health and Brain Development (CERCH). She obtained her Ph.D. in Neurobiology from the University of Washington, and completed her postdoctoral training with Dr. Wylie Vale and the Salk Institute. Prior to joining UM SOM, Dr. Bale was a Professor of Neuroscience at the University of Pennsylvania, where she also co-directed the Penn Center for the Study of Sex and Gender in Behavioral Health and was the Director of Research for the BIRCWH Faculty Scholars.

A nationally-recognized neuroscientist, Dr. Bale is respected for her research on stress as a risk factor for neurodevelopmental disorders and neuropsychiatric disease. She has been the recipient of several awards including the career development award for early career achievement and promise by the Society for Neuroscience, the Richard E. Weitzman Memorial award as exceptionally promising investigator award by the Endocrine Society, the Medtronic Award from the Society for Women’s Health Research for outstanding research that has led to the improvement of women’s health, and most recently, the Daniel H. Efron Research Award from the American College of Neuropsychopharmacology.

Dr. Bale's lab has developed mouse models to study vulnerability to stress dysregulation, assessing sex-specificity, developmental timing, and epigenetic mechanisms involved in programming of the brain, placenta, and sperm in response to stress. Her research has provided novel insight into the increased neurodevelopmental risk to males following prenatal insults, such as maternal stress, and the role of placental sex (XX vs. XY) in buffering effects of gestational insult. Her lab identified OGT expression in the placenta as critical in providing protection to female offspring. Her lab is also making important discoveries linking paternal stress experience to offspring dysregulation through novel epigenetic markers in the sperm. Recently, Dr. Bale has focused on bridging basic and clinical research, translating her work on epigenetic markers in the sperm, and collaborating with Dr. Neill Epperson to mechanistically examine the impact of early life adversity on neuropsychiatric disease in women.
