Stacey M. Schaefer is an affective neuroscientist at the University of Wisconsin-Madison's Institute on Aging. Dr. Schaefer is P.I. of the longitudinal Midlife in the United States National Study of Health and Wellbeing (MIDUS) Affective Neuroscience Project. She received her B.S. in Psychology and Zoology at the University of Wisconsin-Madison and Ph.D. in Psychology with a specialization in Cognitive Neuroscience at the University of Pennsylvania. Her research focuses on identifying the linkages between individual differences in the time course of emotional responses, health, wellbeing, and brain aging, as well as the sociodemographic, psychosocial, and lifestyle factors that moderate those relationships. Dr. Schaefer is also P.I. of a study in collaboration with leaders of the Wisconsin Registry for Alzheimer Prevention examining how emotional processes may differ in preclinical AD, how these emotional differences relate to memory and cognition changes, as well as to tau and amyloid levels (the pathological proteins that build up in AD). Finally, Dr. Schaefer is co-PI of a large R01 study examining how individual differences in the time course of emotional responses (measured with neuroimaging, psychophysiology, and ecological momentary assessment) are important for mental health, stress regulation, the immune system, cognition, and coping with the impacts of the COVID-19 pandemic.
