PRINCIPAL INVESTIGATOR
LINDSAY HALLADAY, PhD
lrhalladay@arizona.edu
Lindsay earned her B.A. in biological psychology from Cal State San Bernardino, where she first started researching neural circuits in the developing basal ganglia, in Sanders McDougall's and Cynthia Crawford's labs. She earned her Ph.D. in behavioral neuroscience from UCLA while working in Tad Blair's lab. Her graduate work investigated the role of neural circuitry underlying defensive action selection. Lindsay then spent four years in metro D.C. as a Postdoctoral Research Fellow in Andrew Holmes's lab at the National Institute on Alcohol Abuse and Alcoholism. Her primary research there examined neural circuitry underlying compulsive alcohol-seeking. Lindsay joined the Psychology Department and Neuroscience Program at Santa Clara University in the fall of 2017 and received tenure in the spring of 2023. The Halladay Lab relocated to the University of Arizona's Neuroscience Department in January 2025. Broadly speaking, the Halladay Lab investigates the neural intersection between reward and aversion. Current research projects aim to identify specific neural circuits mediating allostatic mechanisms related to stress- and/or reward-related behaviors.
We've relocated to the University of Arizona!
