Dr. McGrath is an Instructor in Medicine at Harvard Medical School and Associate Physician at Brigham and Women’s Hospital, where she attends on the Transplant and General Nephrology services.  As an active and successful physician-scientist, she devotes time to both patient care and laboratory-based research. Her clinical interest lies in transplantation and other forms of immune-mediated kidney disease, including glomerulonephritis. Her research is focused on improving our understanding of the mechanisms involved in transplant rejection, and developing innovative therapeutic approaches that will improve outcomes for transplant patients.Her current projects include:

  • Examining the role of the costimulatory molecule, TIM-4, in transplant rejection. By targeting this pathway, she aims to promote the development of regulatory T cells, leading to improved function and survival of solid organ transplants.


  • Assessing the role of IL-17 producing T cells (Th17 cells) in transplant rejection and analyzing the effect of clinically used immunosuppressive agents on the function of these cells.
