Julie Dumas Ph.D.Research Associate Professor
Julie Dumas, Ph. D. is a Research Associate Professor in the Department of Psychiatry and the Clinical Neuroscience Research Unit at the University of Vermont. She got her Ph.D. in Cognitive Psychology from the University of North Carolina at Chapel Hill in 2002 and her B.A. from the University of Virginia in 1996.
Dr. Dumas’ research program examines the neurobiology underlying age-related cognitive dysfunction. We have conducted studies on the interaction of gonadal steroids and neurotransmitter systems and the effects of these interactions on cognition in women after menopause. Specifically, we have examined the interaction of estrogen and the cholinergic system. Current studies are examining the effects of menopause on the dopaminergic system effects on cognition and brain functioning. We also examine the presence of subjective cognitive complaints and the ability of older adults to compensate for age-related cognitive changes.
