Srihari Sundararajan, MD
Dr. Srihari Sundararajan is Chief of Interventional Neuroradiology at University Radiology Group and Rutgers Robert Wood Johnson Medical School. He practices across neurointerventional radiology, interventional radiology, and diagnostic neuroradiology, with a focus on minimally invasive, image-guided treatments of vascular, cerebrospinal fluid, and oncologic disorders of the brain, spine, and head and neck.
He completed his medical degree at SUNY Downstate Health Sciences University, followed by internship at Lenox Hill Hospital. He completed Diagnostic Radiology residency at Rutgers Robert Wood Johnson Medical School, with subsequent fellowship training in Neuroradiology, Interventional Radiology, and Neurointerventional Radiology at the University of Pennsylvania and Weill Cornell Medicine.
Dr. Sundararajan is actively involved in national societies including the Society of NeuroInterventional Surgery (SNIS), Society of Interventional Radiology (SIR), and Society of Vascular and Interventional Neurology (SVIN).
