Dr. Masdeu trained in Psychiatry at the University of Valencia in Spain and in Neurology at Mt. Sinai Hospital in Chicago. He then served as a Fellow in Neuropathology at Peter Bent Brigham Hospital at Harvard Medical School. He was an Assistant and Associate Professor of Neurology at the Albert Einstein School of Medicine in New York, and has served as a Professor and Chair of Neurology at New York Medical College. Dr. Masdeu became a Professor and Chair of Neurology and Neuroscience at the University of Navarre Medical School in Pamplona, Spain. From 2008-2014, Dr. Masdeu was a senior staff physician and scientist in the Section of Integrative Neuroimaging of the Clinical Brain Disorders Branch at the National Institutes of Health. He is chairman of the Neuroimaging Research Group of the World Federation of Neurology. He has been a director of the American Academy of Neurology and president of the American Society of Neuroimaging. Since 2007, he has been Editor-in-Chief of the Journal of Neuroimaging. He is the author of 144 peer-reviewed papers, 62 book chapters, and seven books, including Localization in Clinical Neurology, a standard in the field, now in its 6th edition. Dr. Masdeu joined the Houston Methodist Research Institute in 2014. 

Description of Research

Dr. Masdeu’s main areas of research have been the following:

-Clarifying the neurobiology of Alzheimer’s disease and other neurodegenerative disorders
-Using spontaneous lesion models and/or imaging to map the localization of function in the human brain
-Developing novel neuroimaging signs and implementing neuroimaging as a biomarker of neurological disease
