Dr. Madoff has a strong background in clinical care and has treated many patients with complex oncological problems. His clinical interests are wide-ranging, and have included visceral vascular, hepatobiliary and genitourinary interventions, various embolotherapy and percutaneous biopsy techniques and many specialized therapies within the realm of Interventional Oncology. In particular, Dr. Madoff is world-renowned for his work on preoperative portal vein embolization, a technique used to improve the safety of major hepatic resection. This technique is based on the liver's ability to regenerate and has been used in patients with primary and metastatic hepatobiliary cancer to increase the size of the anticipated liver remnant before surgery. Without this procedure, many patients with potentially resectable disease would not be eligible for curative resection.

Dr. Madoff is a leader in academic Interventional Radiology and has been an invited speaker at numerous national and international meetings. He authored or co-authored over 200 peer-reviewed scientific articles, has written more than 30 book chapters and served as co-editor of four textbooks including Venous Embolization of the Liver: Radiologic and Surgical Practice (2011), Clinical Interventional Oncology (2014) and Interventional Radiology: Fundamentals of Clinical Practice (2019). Dr. Madoff served as Deputy Editor-in-Chief for the Journal of Vascular and Interventional Radiology from 2007 to 2010 and Deputy Editor for Radiology from 2012 to 2017. Dr. Madoff currently serves as founding co-Editor-in-Chief for Digestive Disease Interventions and on the editorial boards of additional publications that include Techniques in Vascular and Interventional Radiology, Seminars in Interventional Radiology, Cancer Biology & Medicine, Chinese Clinical Oncology and Current Oncology Reports. Dr. Madoff is active in many of the major radiological societies including the Radiological Society of North America, the American Roentgen Ray Society, the Society of Interventional Radiology and the Association of University Radiologists and serves on the Board of Trustees of the American Registry of Radiologic Technologists (ARRT). Based on his important contributions to the field, Dr. Madoff was elected Fellow of the Society of Interventional Radiology in 2007, the American College of Radiology in 2015 and the Cardiovascular and Interventional Radiology Society of Europe in 2018.
