Dr. Leite-Morris is an Assistant Professor in the Division of Psychiatry and Department of Pharmacology and Experimental Therapeutics at Boston University School of Medicine and directs a neurochemistry and behavioral neuroscience laboratory at the VA Boston Healthcare System. Dr. Leite-Morris’ primary research interests are in determining the neurochemical mechanisms that underlie the anticipation, intense “craving” and repeated consumption of ethanol and substance abuse. She has established a rodent model of ethanol-self administration paired with current methods of in vivo microdialysis that procedurally separates and quantifies neurotransmitter levels during the different elements of the addiction process. Her methods incorporate a pharmacological approach utilizing novel therapeutic agents including novel positive allosteric modulators of the GABA receptor that culminate in alterations of dopamine, GABA and glutamate.
Dr. Leite-Morris has established a behavioral phenotyping laboratory at the VABHS to examine fear conditioning and stress as they relate to alcohol-directed behaviors in genetically modified mice.Dr. Leite-Morris’ collaborative projects include opiate reward and extinction, fear conditioning, and alcohol and substance abuse in penetrating brain injury and shock wave. Dr. Leite-Morris received her doctorate from the University of Rhode Island in the Department of Biochemisty and Molecular Genetics and completed her NIAAA NRSA Postdoctoral Fellowship at Brown University’s Center for Alcohol and Addiction Studies where she remains an Affiliate Faculty member. She is supported by a grant from NIAAA. Interested students can contact Dr. Leite-Morris at email@example.com.
