Roy Hamilton, M.D., M.S., is an Assistant Professor of Neurology at the University of Pennsylvania. He is board certified in neurology. He graduated from Harvard Medical School and Massachusetts Institute of Technology with degrees in Medicine and Health Sciences Technology. He completed residency in Neurology at the University of Pennsylvania.

His research interest is in the characteristics and limits of functional plasticity in the adult human brain; how the brain reorganizes itself in response to injury, and whether it is possible to enhance the brain's potential for reorganization in order to speed rehabilitation. Dr. Hamilton's studies use a technology known as transcranial magnetic stimulation (TMS) to examine and manipulate the functional anatomy and connectivity of the brain in both healthy and injured states. He has a special interest in patients who may be suffering from a condition known as normal pressure hydrocephalus (NPH), and he evaluates these patients as part of a coordinated effort between the Penn Memory Center and the Department of Neurosurgery at the University of Pennsylvania.

Dr. Hamilton is also director of the University of Pennsylvania School of Medicine Pipeline Program, a multi-tiered neuroscience education program for inner-city high school students in Philadelphia.

David Wolk, M.D. is an Assistant Professor of Neurology in the Cognitive Neurology Division. He is board-certified in Neurology. He completed his medical training at Johns Hopkins University, a Neurology Residency at the University of Pennsylvania, and Clinical Fellowship training in Cognitive and Behavioral Neurology at Brigham and Women’s Hospital/Harvard Medical School. He completed a post-doctoral research fellowship studying memory in Alzheimer’s Disease at Brigham and Women’s Hospital and Harvard University. Prior to his return to Penn, he was an Assistant Professor at the University of Pittsburgh and their Alzheimer’s Disease Research Center.

Dr. Wolk’s research has focused on memory measures and other markers that allow for early detection of Alzheimer’s disease (AD). One of the major challenges in the diagnosis of very early Alzheimer’s disease is differentiating the memory failures associated with the normal aging process from that reflecting early AD pathology. As such, his research currently focuses on memory changes in healthy aging, Mild Cognitive Impairment, and AD using Event-Related Potentials (a form of EEG), MRI (including structural and functional measures), and novel psychometric testing. It is hoped that these methods will contribute to early detection and intervention with emerging treatment modalities.
