Dr. Nandakumar Nagaraja's research interests include neuroimaging in acute ischemic stroke, cerebral amyloid angiopathy, stroke in young adults and disparities in stroke.

Dr. Nagaraja’s primary research focus is to understand the cerebral hemodynamics in acute ischemic stroke using perfusion imaging and magnetic resonance imaging. His research goal is to improve the understanding of ischemic core and ischemic penumbra with neuroimaging.

In the area of cerebral amyloid angiopathy, his research focuses on prevalence, imaging biomarkers, and outcomes using national and Penn State Health datasets. He uses large national datasets to study stroke in young adults and disparities of stroke.

Dr. Nagaraja has served as a principal investigator or co-investigator in several clinical trials related stroke funded by the NIH (StrokeNet) and industry.

Dr. Nagaraja’s primary clinical interests include acute stroke management of ischemic and hemorrhagic stroke and secondary stroke prevention.

Dr. Nagaraja evaluates patients presenting with stroke symptoms (brain attack) for treatment with intravenous thrombolytics and endovascular therapy, optimize medical management of stroke with necessary workup to identify the cause of stroke, and monitor for complications.

In the clinic, Dr. Nagaraja evaluates patients referred for management of stroke. He also follows patients discharged from the hospital to optimize secondary stroke prevention measures, and assess for stroke recovery. He has particular interest in cerebral amyloid angiopathy (CAA) to understand the spectrum of the disease and recovery from hemorrhage due to CAA.
