Ajit Singh Puri

Ajit Singh Puri, MD, DM, DMRE, is a Professor in the Department of Radiology at UMass Chan Medical School, with cross-appointments in Neurological Surgery, Neurology, and the NeuroNexus Institute. His primary clinical focus is Neurointerventional Radiology, where he leads research on stroke interventions and aneurysm treatments. Dr. Puri maintains active collaborations with international multicenter research consortia including the WorldWideWEB Registry and CLEAR Study Group.

Education & Training:

• DM Neuroradiology - Autonomous University of Barcelona, Spain
• MBBS - Jawaharlal Nehru Medical College, India
• DM-Neuroradiology Fellowship - All India Institute of Medical Sciences
• Neuroradiology Fellowships - University of Arkansas for Medical Sciences & Brigham and Women's Hospital
• Residency in Radiology - B.Y.L. Nair Hospital, India

Research Focus: Dr. Puri's research advances neurointerventional techniques for acute stroke and aneurysms. He specializes in mechanical thrombectomy optimization for medium vessel occlusions, endovascular device innovation (WEB, flow diverters), and multicenter clinical trials evaluating thrombectomy systems. His work emphasizes real-world procedural efficacy, complication mitigation, and socioeconomic factors in neurovascular care.

Publication Trends: Recent articles (2023-2025) demonstrate three key themes: 1) Multicenter trials of thrombectomy in extended time windows/distal occlusions, 2) Woven EndoBridge device outcomes for aneurysms, and 3) Flow diverter safety evaluations. His research consistently incorporates propensity scoring, device comparison methodologies, and registry data from international collaborations.
