Rate My Professor Lindsay Halladay

Halladay's research centers on the physiological processes by which neural activity generates behavior, particularly how reward and aversion circuits converge and interact to produce aversive learning, social behavior, and long-term consequences of early life stress. Her lab utilizes in vivo electrophysiology, robust behavioral paradigms, and state-of-the-art technologies to dissect dysfunctional circuitry implicated in psychiatric conditions. Key publications include "Astrocytes enable amygdala neural representations supporting memory" in Nature (2026), revealing astrocytes' critical role in aversive memory; "Genetically diverse mice exhibit divergent domain-specific, sex-dependent behavioral outcomes following exposure to early life stress" in PLOS One (2025); "Lasting impact of postnatal maternal separation on the developing BNST: Lifelong socioemotional consequences" in Neuropharmacology (2023); "A prefrontal-bed nucleus of the stria terminalis circuit in the regulation of fear under uncertain threat" in eLife (2020); and "A corticostriatal circuit involved in regulating punished ethanol seeking" in Biological Psychiatry (2019). Her contributions have advanced understanding of stress-related neural dynamics. Halladay has secured funding through the Young Investigator Award from the Brain & Behavior Research Foundation (2021, supported by the Walder Family), an NIH R15 AREA grant (2021), and a Diversity Outbred Pilot Grant from the Jackson Laboratory (2022).
