Current Research: 

My research and academic interests focus on the study of brain-behavior relationships in the context of aging and age-related, neurodegenerative disease. I use neuroimaging techniques, including structural and functional magnetic resonance imaging (MRI) and positron emission tomography (PET), in combination with measures of cognition and behavior to address research questions on the effects of healthy aging and Alzheimer’s disease on the brain and on the mechanisms of human cognitive aging. A major focus of my research program includes the use of univariate and multivariate network analysis techniques with multiple neuroimaging methods and measures of neuropsychological function, health status, and genetic risk to understand how these factors interact to influence cognitive function as we age. My research also includes the application of these techniques to non-human animal models of aging and age-related disease. I direct the Brain Imaging, Behavior & Aging Lab in the Department of Psychology, have an appointment in the Evelyn F. McKnight Brain Institute, and direct the MRI Morphology Core of the Arizona Alzheimer’s Research Center.
