Dr. Manaye earned her undergraduate degree in Haile Sellassie University of Addis Ababa, Ethiopia in 1974, and her M.D. degree from the University of Aristotle, School of Medicine at Thessalonica, Greece in 1984. She joined the Department of Psychiatry at University of Southwestern Medical Center at Dallas, Texas, as a postdoctoral fellow in 1986 and became Assistant Professor in 1990. She moved to the Howard University School of Medicine in 1999 as an Assistant Professor in the Departments of Physiology and Biophysics. Dr. Manaye became tenured Associate Professor in 2005. Furthermore, she has held an adjunct appointment in the Department of Psychiatry at Howard University School of Medicine.

The mission of Dr. Manaye’s Laboratory of Brain Aging and Neurodegeneration is to understand the basic mechanisms that underlie changes in neurons and glial cells under conditions of normal brain aging and degeneration. Her interests include Alzheimer’s disease and depression in humans, and their associated animal models in rodents and non-human primates.

Dr. Manaye is well-published and well-funded by NIH and private research foundations. She is an active member of several professional organizations including AAAS, Society for Neuroscience, and Women Graduate in Science, International Brain Research Organization, and International Stereological Society. She also serves on Annual Brain Awareness as organizer. Dr Manaye has been invited to serve as board of director for International Behavioral Research Press.
