About

I received my B.S. in Behavioral Neuroscience from Rider University. I earned my Ph.D. in Biology at Johns Hopkins University in the laboratory of Samer Hattar and conducted my postdoctoral work at the University of Maryland School of Medicine in the laboratory of Scott Thompson.

Research interests

The brain continuously processes a diverse array of information, and plasticity of and interactions between specific neuronal circuits are critical regulators of physiology and behavior. This allows organisms to respond to stimuli or changes in the environment and is essential for regulating physiology and behavior. Our goal is to understand how plasticity within neuronal circuits modulates complex behaviors. To tackle this broad goal, we focus on reward related behaviors given their evolutionary importance for survival and the prevalence of symptoms associated with reward in psychiatric disorders. We aim to understand how plasticity of and interactions between specific neuronal circuits integrate information to properly regulate reward related behaviors and how alterations may contribute to psychiatric disorders. Our research program employs a multilevel strategy, from synapses to behavior, combining electrophysiology, imaging, and behavior in mice to understand the neuronal circuit mechanisms responsible for integrating information to regulate behavior.

Teaching interests

My teaching interests include neuroscience ranging from the function of synapses to the regulation of behavior. I am also interested in helping trainees build skills that will be critical for their success as future scientists including communication, experimental design, and hypothesis testing.
