Research Topics:
  • Transplantation immunology
  • Ischemia reperfusion injury
  • Optimization of diagnostic testing in transplantation
  • Myeloma genomics


Dr. Rob Liwski is a Professor of Pathology at Dalhousie University as well as a staff Hematological Pathologist and the Medical Director of the HLA Laboratory at the Queen Elizabeth II Health Sciences Centre in Halifax. He is also the Medical and Scientific Director of the HLA Laboratory at the Canadian Blood Services Head Office in Ottawa. Dr. Liwski serves as the Chair of the Canadian HLA Laboratory Proficiency Testing Committee and is a consultant to the Brazilian Histocompatibility Association (ABH) Proficiency Testing Committee.

Dr. Liwski has developed several optimized HLA antibody testing methods including the Halifax/Halifaster flow crossmatch protocols and the Rapid Optimized Single Antigen Bead (ROB) assay. He was awarded the Canadian Association of Pathologists Junior Scientist Award for his research investigating the role of activated protein C in prevention of ischemia reperfusion injury and cancer metastasis.

Dr. Liwski has been an active member of the histocompatibility community, contributing articles to the ASHI Quarterly and teaching topics in histocompatibility at several venues including ASHI Annual Meetings and Regional Workshops, the Georgetown University Lecture Series, the American Foundation for Donation and Transplantation (AFDT) Histocompatibility Specialist Course, and the Brazilian Histocompatibility Association (ABH) Workshops.

Within ASHI, Dr. Liwski is or has been a member of the Proficiency Testing Committee (since 2014), Proficiency Testing Executive Committee (since 2016), the Scientific Affairs Committee (2015), the ASHI Annual Meeting Planning Committee (2015) and the ASHI Board of Directors (since 2016).
