Jean-Jacques Soghomonian received a doctorate in neuroscience from the University of Aix-Marseille and a Ph.D. in neurological sciences from the University of Montreal. He completed postdoctoral training at the Medical College of Pennsylvania and the University of Pennsylvania and joined the Department of Anatomy and Neurobiology at Boston University School of Medicine in 1998. Dr. Soghomonian maintains an active research program on the anatomical and functional organization of the basal ganglia in the normal brain and in experimental models of Parkinson's disease. Dr. Soghomonian teaches medical histology and medical neuroscience to undergraduate and graduate medical students, and is director of the graduate course Methods in Neuroscience. He currently serves on the MD-PhD admission committee at Boston University School of Medicine and on the qualifying committee in the Department of Anatomy and Neurobiology.
