Krystle Frahm, PhD
Dr. Frahm's research interests focus on how endogenous and exogenous factors disrupt neuroendocrine development and function resulting in long-lasting physiological and behavioral consequences. Current studies are examining the role of glucocorticoid signaling during fetal development and in adulthood using genome-wide analysis and behavioral phenotyping. These collectively will provide insights into how altered hypothalamic output and can contribute to altered energy homeostasis and stress responses in a sex-specific manner.
