Research & Publications

Research Summary

In addition to providing administrative oversight to two major programs at MGH, clinical care, and teaching, I have been conducting clinical research on transplant surgery, vascular reconstruction, tolerance induction without immunosuppression, and urologic voiding dysfunction. I have received funding from grants (Juvenile Diabetes Research Foundation) as a Principle Investigator that aimed to determine the feasibility of induction of islet cell tolerance in the cure of diabetes. I currently have under review a grant that proposes to study the novel approach to genitourinary reconstruction with vascularized composite grafts in collaborations with Plastic Surgery at MGH.            

I have received the following awards in recognition of my excellence in research: a) Investigator Award in Dialysis International for outstanding peritoneal dialysis outcomes; b) Certificate of Merit at the American Roentgen Ray Society for formulating 3D CT technology in living donor kidney imaging; c) Outstanding Contributions to Endourology at the Chinese Urological Association 2007, d) Poster of Distinction at the American Transplant Congress 2008 for excellence in organ allocation and health economics; e) Martin Prize in Research 2008 for innovations in transplantation tolerance; and f) American Urological Association 2014 Outstanding Poster for influence of phytoestrogens in female voiding dysfunction. I have and continue to serve as ad hoc reviewer on editorial boards including NEJM, Am J Trans, Ann of Surg, J Urol, Transpl. I was Editor for Current Opinions in Organ Transplantation for pediatric organ transplantation; National Blood Service grant reviewer in the U.K.; and a four-year term as Member of the Chinese Medical Journal International Editorial Board.
