    Lindsay Clark

    Assistant Professor

    Dr. Clark is a clinical neuropsychologist and assistant professor. She is interested in developing easily disseminable and reliable tools to detect early cognitive impairment, predicting clinical outcomes based on AD biomarkers and modifiable risk factors, and understanding impact of biomarker disclosure in diverse populations.

    Barbara Bendlin

    Principal Investigator; Associate Professor

    My lab studies aging and Alzheimer's disease. I am interested in understanding the interplay of factors that contribute to healthy or pathological brain aging. In particular, the effect of factors that contribute to or protect against the development of Alzheimer's disease.

    Tobey Betthauser

    Research Associate

    Dr. Betthauser is a postdoctoral researcher investigating neuroimaging biomarkers that detect pathological features of Alzheimer's disease. His research has focused on the evaluation and quantification methodology of novel positron emission tomography (PET) radioligands designed to detect neurofibrillary tau tangles, a hallmark pathological feature of Alzheimer's disease. Dr. Betthauser is currently exploring relationships between imaging and other AD biomarkers, and their modifying effects on clinical disease outcomes.

    ADRC Director

    Dr. Asthana is Professor of Medicine; Section head of Geriatrics, VA GRECC Director, and ADRC Director. He specializes in dementia characterization and evaluation of interventions for AD.

  • Gleason_carey

    Carey Gleason

    Assistant Professor

    Dr. Gleason is a clinical neuropsychologist and the Administrative Director of the Wisconsin Alzheimer's Disease Research Center. She conducts studies on the effect of hormones on cognition and brain function and also conducts studies on cognitive and brain factors that make elderly individuals at greater risk for falls.

  • Aalexander

    Andrew Alexander

    Associate Professor

    The research of my group is focused on developing imaging and analysis techniques for the study of human brain function with magnetic resonance imaging (MRI) at 3 tesla. My research group is actively involved in functional MRI techniques, functional MRI of TMS brain stimulation, white matter organization mapping, and structural characterization of brain tissues.

  • Carlsson_cynthia_large

    Cynthia Carlsson

    Associate Professor

    Dr. Carlsson’s research focuses on the effects of vascular risk factors and their treatments on cognition and biomarkers for Alzheimer’s disease in persons at risk for dementia.

  • Christian

    Brad Christian

    Associate Professor

    Dr. Christian leads the PET imaging service in the Wisconsin ADRC. His research involves the development and application of PET methodologies to investigate neurochemical changes in the brain, including studying novel radioligands to characterize neurotransmitter-protein interactions and how they are influenced by the effects of neuropsychiatric disease and psychotropic drugs.

  • Luigi

    Luigi Puglielli

    Associate Professor

    Dr. Puglielli's broad research interests focus on the role that lipid metabolism plays in the regulation of Aβ (amyloid β-peptide) generation and synaptogenesis during both normal aging of the brain and the Alzheimer-type of neurodegeneration. Specifically, we focus on the role played by the ceramide-dependent signaling cascade, and by intracellular cholesterol distribution.
