    Vinay Duddalwar is currently at the Keck Medical Center of USC. 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 Section chief of Abdominal Imaging at USC and 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 renal mass imaging, including contrast enhanced ultrasound as well as radiomics (quantitative imaging). He has funded research currently ongoing in these areas. He has presented over a 100 abstracts at scientific meetings and has authored over 60 peer reviewed articles, reviews and book chapters. 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
