Steven C. Sauk, MD, assistant professor of radiology, has been named chief of interventional radiology for Mallinckrodt Institute of Radiology (MIR) at Washington University School of Medicine in St. Louis effective May 1.

Before Sauk joined MIR in 2021, he served as an attending physician at Northwestern Lake Forest Memorial Hospital, where he treated venous and arterial disease. He developed new service lines such as advanced portal venous interventions, becoming a leader in vascular care. At MIR, Sauk has applied his experience in private practice and collaborates with vascular surgery as the IR liaison. He has strengthened relationships with referring services, particularly within Missouri Baptist. Sauk is a champion of patient-centered consultative interventional radiology and has had a major leadership role in establishing and growing the interventional radiology clinic.

Sauk earned his medical degree from UCLA David Geffen School of Medicine after completing his bachelor’s and master’s degrees in molecular biophysics and biochemistry from Yale University. An alumnus, he completed a diagnostic radiology residency and interventional radiology fellowship at MIR and served as chief resident.

Sauk succeeds James R. Duncan, MD, PhD, professor of radiology, who has served as chief of interventional radiology since 2019. Duncan will continue serving patients, teaching trainees and conducting research, in addition to finishing his tenure as a Carol B. and Jerome T. Loeb Teaching Fellow and remaining an active member of the Academy of Educators.
