Welcome to USC Interventional Radiology Research

Welcome to the Interventional Radiology Research Program within the Division of Vascular and Interventional Radiology at the Keck School of Medicine of the University of Southern California and Keck Medicine of USC. Our research mission is to advance image-guided, minimally invasive care through clinically relevant, patient-centered investigation, innovation, and multidisciplinary collaboration.

Our division maintains focused expertise across the full spectrum of modern Interventional Radiology research, with particular strengths in:

  • Venous and thromboembolic disease, including deep vein thrombosis, pulmonary embolism, endovascular thrombectomy, venous recanalization, and stent reconstruction
  • Portomesenteric and splanchnic venous interventions, including portal vein and mesenteric vein recanalization and treatment of portal hypertension
  • Embolization therapies
  • Interventional oncology, including image-guided tumor-directed therapies
  • Lymphatic imaging and interventions
  • Complex inferior vena cava filter retrieval and advanced venous access
  • Outcomes research, health services research, quality improvement, and value-based care

Faculty and trainees actively participate in clinical trials, investigator-initiated studies, device and technique development, and multidisciplinary translational research. Education and mentorship are integral to our research culture, with learners engaged at every stage of investigation.

We welcome collaboration with students, trainees, clinicians, scientists, and industry partners who share our commitment to advancing the science and practice of Interventional Radiology.
