Dr. 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 then worked as an Assistant Professor in the Department of Physiology and Anatomy at Laval University. He 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’s research focuses on the pathophysiology of Parkinson’s disease and l-DOPA-induced dyskinesia. His laboratory, The Laboratory for the Cellular Biology of the Basal Ganglia and Motor Disorders, is also studying the mechanisms involved in the regulation of GABA-mediated signaling in the basal ganglia and the role of the basal ganglia in sensori-motor learning. The laboratory uses a combination of anatomical, neurochemical and molecular biology techniques.

Dr. Soghomonian teaches Medical Histology and Medical Neuroscience to Medical School and Graduate Medical Sciences students. He is also involved in the teaching of Departmental graduate courses and is director of the graduate course “Methods in Neuroscience”.

Dr. Soghomonian has served as the Graduate Director in the Department. 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.
