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.

Dr. Wolk is accepting new patient appointments through the Penn Memory Center. To schedule an appointment, call 215-662-7810.

Allison Hoffman, an expert on health care law and policy, examines some of the most important legal and social issues of our time, including health insurance regulation, the Affordable Care Act, Medicare and retiree healthcare expenses, and long-term care. Her research aims to bring greater descriptive and analytical clarity to the purposes of health regulation and to deepen our understanding of how health insurance design and regulation both reflects and shapes social consciousness around risk. Hoffman co-edited the Oxford Handbook of U.S. Health Law with I.Glenn Cohen and William M. Sage, which offers the most comprehensive review of U.S. health law in the post-ACA era. Hoffman was awarded the Robert A. Gorman Award for Excellence in Teaching in 2018-19. Her current work examines the legality and ethics of the adoption of Medicaid work requirements, considers the future of long-term care and end of life care policies and regulation, and critiques how economic theory has overly shaped the development of health law and policy.

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.

Dr. McMillan holds a bachelor’s degree in psychology and cognitive neuroscience from Temple University, a master’s of science in psycholinguistics from the University of Edinburgh, and a PhD in psychology from the University of Edinburgh.

Dr. McMillan’s research focuses on identifying cognitive and biological markers of neurodegenerative diseases like frontotempoeral lobar degeneration, amyotrophic lateral sclerosis, Alzheimer’s disease, and Parkinson’s disease. His cognitive research focuses on the social and decision-making mechanisms that contribute to language processing deficits associated with neurodegenerative diseases. His biological research uses neuroimaging, genetics, and biofluids in an effort to improve early diagnosis and predict which protein is causing a disease in patients. Dr. McMillan’s biomarker research leverages sophisticated bioinformatic and statistical approaches to integrate multiple data sources in effort to identify precision medicine approaches for treating individual patients. Ultimately, Dr. McMillan intends to integrate cognitive and biological tests to develop powerful methods for identifying patients for entry into clinical trials and for measuring the efficacy of drug treatments in the context of clinical trials.
