UBMD Medicine





Professional Summary:

I have a broad background in renal medicine with expertise in kidney and pancreas transplantation. I am a transplant physician with UBMD Nephrology and the medical director of the kidney and pancreas transplant program at Erie County Medical Center (ECMC). As a transplant specialist, I care for patients with a history of end-stage kidney disease throughout the transplant experience and my daily activity involves the gamut of the transplantation process: I evaluate and select patients who are ready to undergo kidney and pancreas transplantation, I supervise the care of patients during the posttransplant period and I follow these patients in our longitudinal clinic by providing medical and immunological care to them throughout the lifetime of their transplants. I collaborate with ECMC’s transplant administration to ensure that our transplant patients receive the best possible care. I also review quality outcomes metrics and measures to monitor our program’s progress, and I supervise modifications to our care protocols whenever they are needed. I have a keen interest in promoting living donation at ECMC and am working to establish a robust kidney paired donor (KPD) program so that more live-donor, life-saving transplants can be performed in Western New York.

My research interests are in outcomes research in kidney-pancreas transplantation, e.g., immunotherapy minimization after kidney and pancreas transplantation and the role of various induction protocols in kidney-pancreas transplantation. I have several ongoing research projects that include fellows from the divisions of Internal Medicine and Nephrology.

As a university faculty member and clinical educator for the UBMD transplant team, I conduct bedside teaching and give didactic lectures on key topics in renal and transplant medicine. I believe that a good teacher recognizes differing learning styles and flexes to the strengths of the student in order to teach effectively. As a mentor for the clinical research rotations, I encourage residents to approach their research by asking a simple question that is relevant to the specific demographics of our transplant recipients. I then mentor residents as they write protocols for the Institutional Review Board (IRB) and collect, test, analyze and interpret their data. In this way, I encourage trainees to extend and apply clinical research to improving outcomes for our patients.

I also am involved in developing the renal fellows transplant lecture series and establishing the teaching curriculum for our transplant medicine fellowship program. I train and mentor transplant physicians and nurse practitioners to take leadership positions across the nation in the field of transplant nephrology.
