Bio

Rajiv (Raj) Gupta, PhD, MD is the Enterprise Medical Director of Neuroradiology for Mass General Brigham, Division Chief for Neuroradiology at the Massachusetts General Hospital (MGH), an Associate Professor of Radiology at the Harvard Medical School, and a Lecturer in Nuclear Science and Engineering at MIT. He also directs the Advanced X-ray Imaging Sciences (AXIS) Center at MGH. Raj earned his MD at Cornell University, his PhD in Computer Science at the University at Stony Brook, and MSc Honors (Physics) and BE Honors (Electrical Engineering) from BITS, Pilani. Raj was a Computer Scientist at General Electric conducting research in X-ray imaging, non-destructive evaluation of aircraft engine parts, and computer vision. He also served on the faculty of the University of Southern California, Los Angles in EE-Systems. His research is focused on radiation physics and clinical applications of novel technologies to medical imaging.

Research

My research is focused on three main topics: (1) development and clinical applications of novel X-ray imaging modalities including 5th Generation CT, ultra-high resolution CT, phase contrast X-ray imaging, and dual-energy CT; (2) development of low-cost devices for imaging and image-guided interventions; and (3) study of traumatic brain injury (TBI) using advanced, quantitative MRI techniques.

My lab is building a prototype Static CT system that can be deployed in resource-poor environments. In another project, we are investigating the use of transcranial near-infrared light as a therapy for TBI. Besides multiple government sponsored research grants, I have been an investigator on numerous industry-sponsored clinical trials and have participated in several large industry-sponsored trials. For example, my lab is clinically evaluating a unique photon-counting CT scanner for stroke and other applications.  I am also the imaging PI for a Phase III clinical trial (ClinicalTrials.gov Identifier: NCT00000550) running at nearly 100 sites world-wide that is testing the efficacy of Clazosentan for vasospasm after aneurysmal subarachnoid hemorrhage.
