Overview

Vinay Duddalwar is a Professor of Radiology, Urology and Biomedical Engineering at the Keck School of Medicine at the University of Southern California. He completed his medical education at Nagpur , radiology residencies at Pune, India and Aberdeen, UK. and a fellowship in abdominal imaging and intervention at the University of British Columbia, Vancouver. He was on the faculty at Grampian University NHS Hospitals, Aberdeen UK and then subsequently moved to USC.
He currently is the Medical Director , Imaging for the Norris Cancer Center at USC. His interests are in the field of abdominal oncologic imaging, especially Genitourinary imaging. His research focus is in the field of radiomics, quantitative and multiomic evaluation of neoplasms. He established and leads the USC Radiomics Lab (radiomicslab.usc.edu) which is an interdisciplinary translational research group interested in the development and use of quantitative methods of evaluating imaging data. His lab is at the intersection of quantifying imaging, artificial intelligence and multiomic analysis. The lab is funded by federal, foundation and industry grants and is currently exploring radio genomics, imaging evaluation of angiogenesis, molecular and immune correlates and biomarkers as well as treatment response in various cancers. This includes developing human allied explainable decision support systems He has extensive collaborations with both clinical and translational researchers. He has funded research currently ongoing in these areas. He is an active member of a number of national and international radiology societies. He is a GU section editor for Clinical Radiology as well as reviewer for a number of radiology and urology journals
