My primary research interest is the use of neuropsychological assessment with the geriatric population and neurodegenerative diseases. I am interested in collecting normative data for the geriatric population to enhance the clinical utility of available assessments. As normative data  improves, the accuracy of identifying profiles of various neurodegenerative diseases increases. Previously, I have analyzed neuropsychological, clinical, and behavioral data of various neurodegenerative diseases (e.g. Lewy Body Dementia, Primary Progressive Aphasia, and Alzheimer's disease) with a specific eye toward identifying features/deficits in the very earliest of stages (e.g. pre-dementia/Mild Cognitive Impairment). I am also interested in identifying the role of cerebrovascular dysfunction in Alzheimer's disease. Additional areas of interest include sports related brain injury and Chronic Traumatic Encephalopathy.
