Mehdi received his medical degree from Tehran University of Medical Sciences and completed a postdoctoral fellowship, supported by an Intramural Research Training Award, in Dr. Leggio’s lab at the NIH Clinical Center. During his postdoctoral fellowship, Mehdi conducted several clinical and translational projects, including two major protocols (13-AA-0040 and 13-AA-0043) as the Lead Associate Investigator. His research has been focused on understanding the neurobiology of addictive behaviors and identifying/testing novel therapeutic targets for alcohol and other substance use disorders. He uses a combination of behavioral, pharmacological, genetic, and neuroimaging methods and is also interested in investigating innovative human laboratory approaches that may facilitate the crosstalk between preclinical and clinical research, with a particular focus on behavioral pharmacology and substance use. Another line of research that Mehdi is pursuing includes utilizing big data to characterize biobehavioral substrates of health disparity (e.g., racial differences) in risk/resilience to addiction and other mental health disorders.
