Dr. Mark A. Rossi is an Assistant Professor in the Department of Psychiatry at Robert Wood Johnson Medical School. He received his B.A. in psychology from the University of Michigan-Dearborn in 2009. He received his Ph.D. in Psychology and Neuroscience from the systems and integrative neuroscience program at Duke University in 2015 in the lab of Henry Yin where he used in vivo electrophysiology and optogenetics to study how the basal ganglia regulate motivated behavior. He completed his postdoctoral training in neurobiology in 2021 with Garret Stuber at the University of North Carolina and then at the University of Washington where he used deep brain two-photon calcium imaging, slice electrophysiology, and single-cell sequencing to investigate how lateral hypothalamic circuits guide feeding and obesity. Dr. Rossi joined the faculty of the Child Health Institute of NJ in July 2021.
The Rossi laboratory studies how distributed neural circuits control feeding and motivation. The lab is particularly interested in how diet influences the function of hypothalamic circuitry and how it may be modified in obesity. We use a combination of deep brain two-photon calcium imaging, electrophysiology, and genetic tools to perturb and observe neural activity.
