Dr. Woller’s academic interests reside in thrombosis medicine and anticoagulation management. With a particular interest in the prevention of venous thromboembolic disease, Dr. Woller has served as investigator on multiple ongoing and completed clinical trials including the NIH-funded studies (COAG, GIFT) serving as site PI for GIFT. Dr. Woller is Co-Chair for the American College of Chest Physicians (ACCP) Clinical Practice Guideline that addresses antithrombotic therapy for venous thromboembolic disease, and as was a panelist for the Vascular Access Appropriateness Panel housed at the University of Michigan. Dr. Woller is an invited panelist for the Centers for Disease Control and Prevention (CDC) Risk Assessment Model for the Prevention of Venous Thromboembolic Disease in Medical Patients program.

Dr. Woller is Professor of Medicine, University of Utah School of Medicine, Professor in Research, Intermountain Healthcare, and is a recognized teacher and recipient of the Intermountain Medical Center Housestaff Teaching Award (2011), the University of Utah School of Medicine Outstanding Faculty Teaching Award (2012), and the University of Utah Department of Internal Medicine Outstanding Faculty Subspecialty Teaching Award (2021). Dr. Woller, Fellow of the American College of Chest Physicians (FCCP) and Fellow of the American College of Physicians (FACP), is Utah Chapter Governor of the American College of Physicians (Class of 2025). Dr. Woller's research group was awarded the 2015 U.S. Centers for Disease Control and Prevention (CDC) Healthcare-Associated Venous Thromboembolism (HA-VTE) Prevention Challenge Award.

Dr. Woller received his medical degree from Northwestern University Medical School in 2000. Dr. Woller completed his residency at the University of Utah Hospital (2003) then served as Chief Medical Resident in 2003-04.
