After earning a BA in Neuroscience from New York University and gaining research experience as a lab technician at the Salk Institute, Justin joined the Kravitz lab in 2020. His research focuses on understanding the neural circuits that drive motivated behaviors. Using a combination of behavioral assays, optogenetics, and calcium imaging, he investigates how striatopallidal circuits regulate feeding behavior and how their activation can stimulate feeding even in the absence of physiological hunger. Ultimately, his work aims to contribute to the development of novel therapies for treating diet-induced obesity.
