Biosketch
Dr. Pina received her PhD in Behavioral Neuroscience from Oregon Health & Science University in 2016. Her graduate research focused on mapping the neurocircuitry involved in cue-induced drug seeking behavior. She then completed a postdoctoral fellowship in the Department of Pharmacology at the University of North Carolina at Chapel Hill. In her postdoctoral work, she identified several key cortical neuromodulatory systems that support excessive alcohol use and related behavioral pathologies. Dr. Pina joined the University of Maryland School of Medicine as Assistant Professor in the Department of Neurobiology in 2022.
Dr. Pina's research focuses on identifying the distinct neural circuits and signaling mechanisms that regulate excessive drug use and determining how plasticity within these systems can contribute to comorbid neuropsychiatric conditions. Her lab integrates behavioral models with electrophysiological, biochemical, and genetic approaches to identify the molecular and cellular adaptations that occur in the brain following repeated exposure to alcohol and other drugs of abuse. Dr. Pina is especially interested in how disrupted serotonin signaling can drive aggression and contribute to the development of anxiety and depression-like behavior.
