PhD
Professional Summary:
Research in my laboratory is focused upon distinct projects in the fields of Behavioral Neuropharmacology and Neuroimaging of Addiction and Substance Abuse. Our research is based on the notion that there are specific genetic and epigenetic vulnerabilities that significantly contribute to Reward Deficiency Syndrome (RDS) of which addiction is a part of.
My lab utilizes molecular, behavioral, and imaging (Positron Emission Tomography, MRI, CT, Autoradiograpjy) methods in animal models as well as how these models contribute to clinical data as part of several ongoing clinical translational studies.
