Mary-Anne Enoch, M.D., (Staff Scientist) has been with LNG since 1995. As a Principal Investigator on human research protocols, she has collected large, comprehensive psychiatric and electrophysiological datasets of U.S. Caucasians, Plains American Indians and Southeastern American Indians. Her research interests include the influence of genes in biological pathways on addiction, the interactive effects of childhood trauma and stress-related genes on vulnerability to alcoholism-related behaviors, and the use of intermediate phenotypes such as electrophysiological measures and dimensional anxiety for understanding the genetics and neurobiology of alcoholism and co-morbid disorders. Dr Enoch is a longstanding member of the NIH Neuroscience IRB.
