Dr. Jaywant is dedicated to improving approaches to neuropsychological assessment and treatment following acquired brain injury and neurologic disease. He has published several scientific articles in peer-reviewed journals spanning disciplines of neuropsychology, psychiatry, neurology, and rehabilitation medicine. He has presented his work at national and international conferences. His research at Weill Cornell Medicine focuses on using resting state functional neuroimaging to understand brain changes underlying cognitive dysfunction in stroke, and developing and evaluating cognitive/behavioral interventions targeted at these brain network abnormalities to improve cognitive functioning. He is also interested in understanding the intersection between depression and cognitive impairment after stroke and developing treatments to address the comorbidity.

Dr. Jaywant was the attending neuropsychologist on NewYork-Presbyterian Hospital/Weill Cornell Medical Center’s COVID Recovery Unit.
