Research

The Department of Surgery has been involved in basic science, translational, investigator initiated, and clinical trials for many years. Each year our residents and faculty have had a strong presence in OU Tulsa’s annual Research Forum where we have won many awards. We are proud of the contribution our faculty and residents have made in their research endeavors.

The OU Vascular Clinic has been very active in 2020, and many opportunities have arisen for our trainees over the last year. The department has published 36 peer-reviewed journal articles and a patent on therapeutics to the spinal cord in spinal cord pathology. Additionally, the department has conducted 37 presentations on the local, regional, and national levels, and is involved in a number of clinical trials. Below is a list of current publications and ongoing clinical trials.
