James

James M. Mathew, PhD

Dr. James M. Mathew obtained his PhD from the prestigious School of Biological Sciences at Madurai Kamaraj University, India. He came to the USA in 1989 for a post-doctoral fellowship in transplant immunology at Washington University in St. Louis, and then in 1994 joined the faculty of the University of Miami, Florida. In 2007, he moved to Northwestern University, where he is now Professor of Surgery and Microbiology-Immunology as well as the Director of Immune Monitoring Core of the Comprehensive Transplant Center.

Dr. Mathew’s research is on the immunology of clinical transplantation. The major thrust has been on the use of donor bone marrow or hematopoietic stem cell infusions for transplant tolerance induction. Recent studies also included the use of regulatory T cells (Tregs) as potential tolerance inducers in transplant and autoimmune patients. Latest, he directed the development of antigen-specific Treg expansion technology which is poised to be used in a phase-I clinical trial in kidney transplant patients.

Dr. Mathew has more than 250 peer reviewed publications comprised of original scientific articles, reviews, book-chapters and scientific presentations. He is a member of most transplant-related scientific organizations and has served in many committees and review panels.

His addition to the Scientific Board of TRACT Therapeutics as the Research and Development Advisor will greatly enhance its current and future portfolios.
