Surgery, Abdominal Transplant Surgery

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.

Selective impact on regulatory T cells with sustained functional phenotypes by the interleukin-2 mutein VIS171 in a nonhuman primate model.

Journal article Am J Transplant · July 2026 The interleukin-2 mutein, VIS171, was engineered to extend half-life and enhance selective binding and expansion of regulatory T cells (Tregs) expressing high levels of the trimeric interleukin-2 receptor. This study evaluated the effects of VIS171 on immu ... Full text Link to item Cite

A novel immunoglobulin G- and immunoglobulin cleaving enzyme MG (IceMG), for antibody-mediated rejection.

Journal article Am J Transplant · June 2026 Antibody-mediated rejection remains a significant barrier to successful outcomes in both allotransplantation and xenotransplantation. In this study, we investigate the efficacy of a novel recombinant endopeptidase, IceMG, which simultaneously cleaves immun ... Full text Link to item Cite
