CHET Associate Director for Research and Community Engagement: Lauren Whitehurst, PhD
Assistant professor in the department of psychology at the University of Kentucky. Dr. Whitehurst鈥檚 research seeks to define 鈥済ood鈥 sleep and how we can leverage it to support healthy cognition and combat disease and cognitive decline. The major themes of her work are centered around investigations of both central (e.g., electroencephalographic) and autonomic (e.g., electrocardiographic) indicators of sleep and their contributions to cognition. She also examines how stress-sleep interactions impact cognitive function and the importance of sleep to the development of accelerated or pathological cognitive decline (e.g., dementia/Alzheimer鈥檚 disease). She is particularly interested in how the lack of access to restorative sleep can play a role in creating or exacerbating disparities in cognitive health for communities historically underserved by science and medicine in the US. Lauren Whitehurst received her. BS in psychology and an MA in experimental psychology from James Madison University in 2011 and 2013, respectively. She completed her PhD in psychology from the University of California, Riverside in 2018 and completed her training as a Chancellor鈥檚 Postdoctoral Fellowship in the Center for Health and Community and the department of psychiatry at the University of California, San Francisco in 2020.
