Alberto Ascherio, MD, DrPH, is a Professor of Epidemiology and Nutrition at the Harvard T. H. Chan School of Public Health and a Professor of Medicine at the Harvard Medical School. Dr. Ascherio trained in internal medicine at the University of Milan, and subsequently practiced medicine and public health in Latin America and Africa. He completed his doctoral degree in epidemiology at the Harvard T. H. Chan School of Public Health. Dr. Ascherio’s research is primarily devoted to finding the causes of multiple sclerosis (MS), Parkinson’s disease (PD), and amyotrophic lateral sclerosis (ALS). Since 1997, he has directed the investigation of neurodegenerative diseases in several large cohorts.  Among the most notable discoveries to which he has contributed are the key roles of infection with the Epstein-Barr virus, vitamin D insufficiency, and cigarette smoking as risk factors for MS, the importance of vitamin D status as a determinant of MS progression, the role of caffeine consumption and urate as negative risk factors for PD and of urate elevation as a promising therapeutic strategy, and the identification of positive and negative environmental risk factors for ALS.
