William C. Mobley, M.D., Ph.D.

Associate Dean of Neurosciences Initiatives; Distinguished Professor of Neurosciences; Executive Director, Down Syndrome Center for Research and Treatment; Florence Riford Chair of Alzheimer’s Disease Research, University of California, San Diego


Dr. William Mobley has a distinguished record of academic achievement and is considered one of the most prominent academic neurologists in the US. He has an international reputation for his research on degenerative disease of the central nervous system as well as being a leader in translational medicine, bridging clinical and basic science.

Dr. Mobley came to UCSD in June 2009 from Stanford University in Palo Alto, Calif., where he served as the John E. Cahill Family Professor in the Department of Neurology and Neurological Sciences and was the founding director of the Neuroscience Institute. Dr. Mobley is the recipient of both the Zenith Award and the Temple Award from the Alzheimer’s Association and was chosen to receive the Cotzias Award of the American Academy of Neurology in 2004. Dr. Mobley is Past President of the Association of University Professors of Neurology, of the Professors of Child Neurology, and of the International Society for Developmental Neuroscience.  He is a Fellow of the Royal College of Physicians and in 2006 was named a Fellow of the American Association for the Advancement of Science.
