Our Team

Under the direction of Dr. Donald Arnold, Dr. John Kelton and Dr. Ishac Nazy, the laboratory has over 30 years of research into immune mediated platelet disorders. Investigations have produced over 300 journal articles and book chapters in collaboration with other investigators, including Dr. Theodore Warkentin. Landmark studies have been published in high impact journals including The New England Journal of Medicine and Blood that have changed patient management and understanding of platelet disorders.

In collaboration with the McMaster Centre for Transfusion Research the laboratory’s bench to bedside research has a direct impact on patient management and health outcomes. The laboratory currently supports 3 core faculty investigators and 9 staff including research coordinators and research assistants. Education is integral to our research, and the laboratory currently supports 3 graduate and 3 undergraduate students.



Dr. Ishac Nazy

Scientific Director

Dr. Ishac Nazy is an Associate Professor in the Departments of Medicine and Biochemistry and Biomedical Sciences at McMaster University, and the Scientific Director of the McMaster Platelet Immunology Laboratory. Dr. Nazy’s research interests are in the specific interactions between antibodies and their target antigens on platelets, leading to thrombocytopenia and/or thrombosis. His translational research with the lab capitalizes on technologies in the fields of immunology, biochemistry, and molecular biology to transfer basic science findings to the clinical practice for improved patient care.



Dr. Donald Arnold

Co-Medical Director

Dr. Donald M. Arnold is a Professor in the Department of Medicine at McMaster University, and Director of the McMaster Centre for Transfusion Research. Dr. Arnold’s focus of research is on platelet disorders including immune thrombocytopenia. Other research areas include blood transfusion practices, optimal utilization of blood products, blood safety and novel treatments. Dr. Arnold is the lead investigator for several multicentre clinical trials in Hemostasis and Transfusion Medicine and has built a translational research program in blood disorders that includes a basic serology laboratory. Dr. Arnold has received funding from the Canadian Institutes of Health Research and Canadian Blood Services for his research.



Dr. John Kelton

Co-Medical Director

Dr. John G. Kelton is the co-medical director of the McMaster Platelet Immunology Laboratory and the Executive Director of the Michael G. DeGroote Initiative for Innovation in Healthcare, McMaster University, Hamilton.

Dr. Kelton’s research career has focused on thrombocytopenia with a particular focus on pregnant patients with platelet and other bleeding disorders and other thrombocytopenic disorders. His basic research studies have included more than 30 years of study of heparin-induced thrombocytopenia (HIT) including its pathophysiology and its treatment. Studies investigating approaches to the diagnosis of platelet disorders in pregnant women and drug-induced thrombocytopenia led to the establishment of the Ontario Reference Platelet Typing Laboratory, now called the McMaster Platelet Immunology Laboratory. Recent studies have focused on clotting disorders associated with both COVID-19 vaccines and infections triggered by COVID-19. Dr. Kelton has received numerous awards including honourary degrees, international awards and recognitions for his research, and membership to the Order of Canada.

Lab Staff

James (Jim) Smith

Research Associate/Technical Director
Jim Smith

Jim started his career studying cancer markers using monoclonal antibodies and glycoprotein-specific assays. He brought this technology to the Platelet Immunology Laboratory for investigation of mothers who make antibodies to their babies and cause bleeding. The assays changed how these pregnancies are managed and led to discovery of new antibodies and antigens. Further research led to discovery of the platelet Fc receptor, which plays a major role in heparin-induced thrombocytopenia. At the beginning of the Covid pandemic, Jim developed an EIA to measure anti-spike and –RBD antibodies to monitor post-infection immunity. Currently Jim is refining PF4-dependent platelet activation assays for confirming diagnosis of VITT.

Jane Moore

Research Coordinator
Jane Moore

Jane has worked in Platelet Immunology for more than 40 years now. During this time, she as played a critical role in developing a bank of frozen serum samples from patients with various platelet disorders, (>1000 heparin induced thrombocytopenia (HIT), >1000 immune thrombocytopenia, >500 thrombotic thrombocytopenia purpura (TTP), >200 COVID/vaccine reactions) which has allowed the McMaster Platelet Immunology Lab to be a global leader in research in these areas. Her research has focused on HIT, TTP, and COVID-19. Jane has coordinated clinical testing and research that has helped advance our understanding of these severe platelet disorders. She has been a resource for technology and information for numerous colleagues, collaborators, students, and staff, and she has been a co-author on over 60 papers.
