Zeying Du

Zeying Du, M.D., Ph.D. is a Laboratory Immunologist and Associate Director of Histocompatibility Laboratory at the Mayo Clinic in Jacksonville, Florida. She previously served as Director of Clinical Histocompatibility Laboratory and Assistant/Associate Professor in the Department of Pathology and Laboratory Medicine at Loyola University Medical Center, Illinois.

• Education: MD (1986), MS (1989), PhD (1998), Postdoctoral Fellow in Immunogenetics (2008), Director-in-training Fellowship in Transplant Immunology (2010)
• Professional Memberships: Member of American Society of Transplantation and Cellular Therapy (ASTCT), International Society of Heart and Lung Transplantation (ISHLT), American Society of Histocompatibility and Immunogenetics (ASHI)

Dr. Du’s clinical and research interests focus on identifying pre- and post-transplant biomarkers of immunological risk to improve solid organ transplant outcomes and using genetic markers for hematopoietic cell transplant donor selection to reduce graft-versus-host disease. Her work has emphasized HLA typing, next-generation sequencing, and transplant immunogenetics.

Her 15 most recent publications (2015–2025) center on HLA allele discovery, antibody-mediated rejection in organ transplant recipients, and immunogenetic risk factors in transplantation. These studies leverage advanced sequencing technologies to refine histocompatibility testing and improve donor-recipient matching.

• Scientific Awards:
  • Paul E. Strandjord Young Investigator Award (2010)
  • Extraordinary Young Investigator Award (2000)
  • Second-place Award for Progress in Natural Sciences (1998)
  • Servier Young Investigator Award (1998)
  • Presidential Scholarship (1998)

Dr. Du actively participates in HLA laboratory inspections (College of American Pathologists, ASHI), contributes to scientific review panels (ISHLT, ACHI), and leads histocompatibility testing at Mayo Clinic’s laboratory. Her research integrates clinical immunology with genetic analysis to advance precision medicine in transplantation.
