Dr. Browndyke is an Associate Professor of Geriatric Behavioral Health in the Department of Psychiatry & Behavioral Sciences.  He also holds affiliate faculty appointments with the Duke Brain Imaging & Analysis Center (BIAC), Duke Institute for Brain Science (DIBS), Center for Cognitive Neuroscience (CCN), and the Duke Center for Geriatric Surgery.  He has dual appointment to the Duke University Medical Center and the Durham VA Medical Center, the latter of which is where his clinical work is currently conducted. 

Dr. Browndyke's research interests include the development and use of functional and structural neuroimaging biomarkers for perioperative contributions to delirium and later dementia risk, monitoring of late-life neuropathological disease progression, and intervention/treatment outcomes.  His research also involves the differential expression of cognitive and behavioral characteristics of late-life postoperative cognitive dysfunction and delirium and their association with later dementia risk.

Dr. Browndyke's clinical expertise is focused upon adult and geriatric populations with an emphasis in the assessment, diagnosis, and treatment of dementia and related disorders, as well as forensic/medicolegal evaluation of adults and US veteran patient populations.
