Research

Toxic stress encountered early in life contributes to an elevated lifetime risk for a broad range of negative outcomes including depression, anxiety, PTSD, cognitive dysfunction, and attentional problems. However, the mechanisms through which stress increases risk for negative outcomes remains poorly understood. The focus of my lab is to understand how adverse experiences encountered early in life alter the trajectory of neural and behavioral development and the genetic mechanisms supporting those changes. We approach these questions through both an evolutionary and developmental lens, with the hypothesis that stress serves as a signal of the quality of the surrounding world for the developing brain. This signal drives changes in the timing of regional brain development to support proximate goals of survival and reproduction, with long-term implications for the expression of pathological behavior. To this end, the lab induces stress in developing mice through manipulation of maternal resources and focuses on the development of multiple brain centers, including the social behavioral network, limbic, paralimbic, and cortical brain areas, and behaviors associated with the development of each. Throughout this work we use an interdisciplinary and vertically integrated approach spanning from genes to behavior and collaborate heavily with researchers focused on studying the impact of various form of stress on neurodevelopment in human populations.
