Dr. Fatemi received his medical degree from the Medical University of Vienna, Austria in 1999. After graduation, he served as a researcher and lecturer at the Institute for Medical Chemistry in Vienna and at the Department of Pediatrics at the Vienna General Hospital. He then moved to the United States to pursue a postdoctoral fellowship in neurogenetics and neuroimaging at Johns Hopkins University School of Medicine in 2001.
During this initial period, Dr. Fatemi collaborated with a team of scientists and developed new imaging methods in patients with leukodystrophies (rare genetic diseases that affect the brain's white matter) and coordinated an internet-2 based imaging network for these diseases. He then left Kennedy Krieger Institute to train in general pediatrics and then completed a child neurology residency at the Massachusetts General Hospital, an affiliate of Harvard Medical School. Dr. Fatemi returned to the Kennedy Krieger Institute in 2008 as faculty.
He is a member of the Child Neurology Society, the International Child Neurology Association, the Society for Neuroscience, the American Academy of Neurology and the International Society for Magnetic Resonance in Medicine. He has served as ad hoc reviewer for the Journals Child Development and American Journal of Neuroradiology.
