Research:

The prefrontal cortex provides top-down control over limbic system activity and integrates perceptions, memories, and emotions to guide behavior. These functions depend in part on a homeostatic balance between glutamatergic and GABAergic neurotransmission. Psychological stress has been shown to disrupt this balance, contributing to the development of psychiatric disorders such as anxiety and depression. Specifically, chronic stress induces hypoactivity of the prefrontal cortex in a sex-dependent manner. Inhibitory parvalbumin interneurons are likely contributors to hypofrontality as these cells dynamically regulate activity and plasticity according to development and experience. My research focuses on how chronic stress perturbs parvalbumin cells at a molecular and network level, and takes lessons from GABAergic system maturation and critical periods of plasticity to investigate therapeutic avenues aimed at restoring PFC functioning. I use behavioral models along with molecular and opto/chemogenetic techniques to study this interaction between stress, excitatory/inhibitory balance, and affective disorders.
