Dr. Steven E. Arnold is Professor of Psychiatry and Neurology at the University of Pennsylvania, Philadelphia, PA. After receiving his M.D. from Boston University, Arnold completed residency training in psychiatry at the New York State Psychiatric Institute/Columbia Presbyterian Medical Center in New York and residency training in neurology at the University of Iowa Hospitals and Clinics in Iowa City. He also completed fellowship training in behavioral neurology/cognitive neuroscience and was a post-doctoral associate in neuroanatomy in Iowa. Arnold is board certified in both psychiatry and neurology. He is currently Director of the PENN Memory Center of the University of Pennsylvania Health System and Associate Director and Clinical Core Leader of the Alzheimer's Disease Core Center, Director of the Geriatric Psychiatry Section in the Department of Psychiatry, Director of the Cellular and Molecular Neuropathology Program in the Center for Neurobiology and Behavior, and Associate Director of the University of Pennsylvania's Institute on Aging.
Arnold has authored more than 160 scientific articles, and his research has garnered numerous awards. He has conducted longstanding research on neurodegenerative disease pathology in relation to cognitive decline in late life and leads a broad clinical and translational research program examining brain and mind aging. Major interests currently include clinical biomarker identification of neuropathology in the aging brain, vascular risk factors for dementia, the long-term neurobiological effects of stress, anxiety, and depression on memory and risk for dementia, and protective factors that account for cognitive resilience in aging. Studies span clinical trials, phenomenology and neuropsychology, molecular neuroimaging, biochemical biomarkers, epidemiology-scale molecular neuropathology in postmortem tissues, and rodent models of chronic stress effects on aging, behavior, and neuropathology.
