Research Topics:
  • Histocompatibility for solid organ and hematopoietic stem cell transplantation
  • Assay optimization
  • HLA typing and antibody testing
  • Transplant Immunology


Dr. Anna Greenshields completed her PhD and a MITACS fellowship at Dalhousie University. She then pursued a clinical ASHI fellowship at the Halifax HLA laboratory, becoming a Diplomat of the American Board of Histocompatibility and Immunogenetics and certified as an HLA laboratory director for solid organ and HSC/BM transplantation.

Currently, Dr. Greenshields acts as the Assistant Director of the Halifax HLA Laboratory at Nova Scotia Health and holds an Assistant Professorship in the Department of Pathology at Dalhousie University.
