Overview
During my career as an academic surgeon, I have had the privilege of leading and/or participating in a diverse portfolio of hypothesis-driven research projects. These projects have centered on the immunology of surgery and transplantation, including both cellular and antibody-mediated immune responses. During my training I studied the response of hyper-sensitized recipients to allogeneic liver transplantation, and am currently studying means of reducing immunologic memory that might allow more successful transplantation in sensitized recipients. This immune response involves pathways of coagulation, antibody-mediated rejection, and cellular rejection and current work in my lab involves these three pathways. The other major focuses of my work have been co-stimulation blockade and immune cell depletion as approaches to immunologic unresponsiveness or tolerance. My research group has been involved in translational and clinical research to develop these mechanistic tools for the benefit of human organ transplant recipients.

Back-to-base Versus In-transit Machine Perfusion in Donation After Circulatory Death Liver Transplantation: Insights From a National Registry.
Journal Article Transplant Direct · April 2026 BACKGROUND: Normothermic machine perfusion (NMP) improves utilization of extended criteria liver grafts, but the optimal delivery strategy-whether in-transit or back-to-base-remains uncertain. METHODS: Adult recipients of donation after circulatory death ( ...
