Former Director of RP-CNBI
Member Chief, Division of Cognitive Neuroscience, Department of Psychology and Behavioral Sciences, St. Jude Children's Research Hospital
Dr. Hampstead is a board-certified Clinical Neuropsychologist who earned his PhD in Clinical Psychology (Neuropsychology emphasis) from Drexel University. He was the Stanley Berent, Ph.D., Collegiate Professor of Psychology in the Department of Psychiatry at the University of Michigan, Staff Neuropsychologist in the VA Ann Arbor Healthcare System, and Clinical Core Leader of the NIA funded Michigan Alzheimer’s Disease Research Center. Dr. Hampstead’s research focuses on non-pharmacologic approaches to maximize cognitive functioning in older adults across the dementia spectrum. Specifically, he uses cognition-oriented treatments and non-invasive brain stimulation to enhance cognition, typically within the context of a randomized controlled trial format. Dr. Hampstead integrates these techniques with functional and structural neuroimaging in order to predict treatment response, identify the neuroplastic changes following treatment, and plan/develop new interventions. Ongoing work integrates amyloid and tau positron emission tomography (PET) in order to better characterize participant characteristics associated with treatment response. He has maintained continuous federal funding for his work since earning his doctorate (20+ years), with most support from the Department of Veterans Affairs and National Institute on Aging.

She earned her doctorate degree in the neuropsychology track at the San Diego State University / University of California San Diego Joint Doctoral Program in Clinical Psychology, and completed internship at the Ann Arbor VA and postdoctoral fellowship at the University of Michigan before joining the faculty in 2018.
Dr. Burton’s clinical and research interests primarily involve understanding the cognitive effects of health conditions like neurodegenerative dementias and schizophrenia, and developing psychosocial interventions to improve wellness and functioning for these individuals. She serves as the University of Michigan Site Principal Investigator for the Wellness Study, a multisite clinical trial evaluating two group wellness interventions for people living with dementia and their care partners. In addition to her role in RP-CNBI, she is a faculty neuropsychologist in the Neuropsychology Section and PREP early psychosis program, and an investigator in the Level Up Lab in the UM School of Social Work.
Kyler Mulhauser, Ph.D.
Clinical Assistant Professor

Site Principal Investigator, mSMT Study
Dr. Mulhauser is a clinical neuropsychologist and Clinical Assistant Professor in the Department of Psychiatry at the University of Michigan Medical School. He earned his Ph.D. in Clinical Psychology with an emphasis in Neuropsychology from Saint Louis University and completed his postdoctoral fellowship in Clinical Neuropsychology at the University of Michigan. His clinical and research interests include cognitive aging, mild cognitive impairment, Alzheimer’s disease and related dementias, and the effects of substance use on cognition. He is an investigator with the Michigan Alzheimer’s Disease Research Center, where he contributes to the clinical characterization of older adults across the spectrum of cognitive aging. His broader research seeks to identify modifiable factors that influence cognitive health and functioning in later life and to evaluate approaches for improving cognitive outcomes. Dr. Mulhauser serves as the University of Michigan Site Principal Investigator for the mSMT Study, a multisite clinical trial evaluating a behavioral memory intervention for individuals with mild cognitive impairment.
Patrick Pruitt, Ph.D.

He completed post-doctoral fellowships at the Institute of Gerontology at Wayne State University and the Department of Radiology at Oregon Health and Science University, as well as performing data analysis at the Alzheimer’s Clinical & Translational Research Unit in the Department of Neurology at Massachusetts General Hospital. Dr. Pruitt is interested in characterizing how to effectively use neuroimaging modalities as outcome measures of clinical trials of age-related cognitive decline, as well as applying principles of Philosophy of Science to studies using neuroimaging data to answer research questions.
Quentin Devignes, Ph.D.
Postdoctoral Fellow
Department of Psychiatry, University of Michigan
Dr. Devignes received his PhD in Neuroscience from the University of Lille in France. His work has been focused on elucidating the pathophysiological mechanisms underlying neuropsychiatric symptoms in various disorders, including Parkinson’s disease and posttraumatic stress disorder, using cutting-edge neuroimaging techniques. He joined the Department of Psychiatry at the University of Michigan Medical School as a postdoctoral research fellow in March 2024, where he has been working on evaluating the potential of neurostimulation (tDCS and TMS) as a non-pharmacological intervention for aging populations and its effects on the brain’s structure and functioning.
