Description of Research Expertise

My research is motivated by the need to better understand the pathophysiology of brain dysfunction. Specifically, my interests include the neural basis of neuropsychiatric disorders and cognitive aging, including changes in social-emotional processing, memory and decision-making. Over the last two decades I have built an arsenal of skills in cognitive and behavioral neuroscientific methods, including psychophysical testing, EEG, structural and functional MRI, diffusion tensor imaging and magnetic resonance spectroscopy, that are useful for evaluating brain-behavior associations. The primary purpose of my research is to strengthen empirical knowledge about brain and behavior associations to better understand cognitive disturbances, particularly in neuropsychiatric and aging populations. My long-term goal is to use advanced multimodal cognitive neuroscientific approaches to facilitate early identification of individuals at-risk for neuropsychiatric or neurodegenerative disease.
