Frank M. Longo, MD, PhD
George E. and Lucy Becker Professor in Medicine
Professor of Neurology & Neurological Sciences

Dr. Longo is chair of the Department of Neurology and Neurological Sciences, the George E. and Lucy Becker Professor of Medicine, and director of the Stanford Alzheimer’s Translational Research Center. His clinical interest include Alzheimer’s disease and other neurodegenerative disorders.  His research team is developing new drugs that are focused on the modulation of fundamental cell signaling pathways that are involved in neurodegeneration. These pathways can be regulated by known protein growth factors but such proteins cannot be used as drugs. Dr. Longo’s team has pioneered the development of the first small molecule, drug-type compounds that can mimic key parts of growth factor proteins and achieve their potent effects on preventing or reversing degeneration. Work in Alzheimer’s mice has been extremely promising and efforts are now underway to bring the first of these compounds to human trials.
