Penn Memory Center Leadership
Directors
Jason Karlawish, MD

Dr. Jason Karlawish is a professor of medicine, medical ethics and health policy, and neurology at the University of Pennsylvania Perelman School of Medicine. He is board-certified in geriatric medicine. He was educated at Northwestern University, the Johns Hopkins Medical Institutions, and the University of Chicago.
Dr. Karlawish is a Senior Fellow of the Leonard Davis Institute of Health Economics, Senior Fellow of the Penn Center for Public Health Initiatives, fellow of the University of Pennsylvania’s Institute on Aging, director of the Penn Program on Precision Medicine for the Brain (P3MB), Co-Associate Director of the Alzheimer’s Disease Research Center, and co-director of the Penn Memory Center. He is also director of the Alzheimer’s Disease Research Center’s Outreach, Recruitment and Education Core and the center’s Research Education Component.
His research focuses on aging, neuroethics, and policy. He has investigated issues in dementia drug development, informed consent, quality of life, paradoxical lucidity and theory of mind in dementia, research and treatment decision-making, and voting by persons living with dementia. He is the project leader of makingsenseofalzheimers.org, a creative space for understanding the past, present and future of Alzheimer’s disease. He is the author of The Problem of Alzheimer’s: How Science, Culture and Politics Turned a Rare Disease Into a Crisis and What We Can Do About It, and the novel Open Wound: The Tragic Obsession of Dr. William Beaumont.

David Wolk, MD

Dr. David Wolk is an associate professor of neurology in the Cognitive Neurology Division of the University of Pennsylvania Perelman School of Medicine. He is board-certified in Neurology.
Dr. Wolk is the director of the Clinical Core and co-associate director of the Alzheimer’s Disease Core Center and is co-director of the Penn Memory Center. 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 also completed a post-doctoral research fellowship studying memory in Alzheimer’s disease there. 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. 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 those reflecting early Alzheimer’s disease pathology. As such, his research currently focuses on memory changes in healthy aging, Mild Cognitive Impairment, and Alzheimer’s disease 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.

Joe Kable, PhD

Joe Kable, PhD is the Baird Term Associate Professor of Psychology at Penn. Research in his lab is concerned with how people make choices, and the neurophysiological mechanisms underlying decision-making. This work combines approaches from experimental economics, the psychology of judgment and decision-making, and social and cognitive neuroscience.
Recently Dr. Kable has used fMRI to show how the subjective value people place on immediate and delayed rewards is represented in a common neural currency. Some broad questions motivating his current research include: How seriously do people’s choices deviate from rational choice theory, and what do the neural value signals in such situations help explain about these deviations? How does decision making differ across individuals, and what are the sources—psychological, genetic, neural—of such individual differences?
Dr. Kable earned his B.S. in chemistry from Emory University and his PhD in neuroscience from University of Pennsylvania.
