Researchers of hematopathology study diseases of hematopoietic cells which originate from the bone marrow and contribute to the cellular components of blood. These components include red blood cells, white blood cells, and platelets. Researchers also investigate the nature of disease of the hematopoietic system and related organs, including the bone marrow, spleen, thymus, lymph node and vasculature. As such, diseases of this system are myriad and include hereditary and congenital disorders, as well as acquired disorders. Complicating matters further, hematopathology disorders may be immunological in nature as well. It is not surprising that researchers involved in hematopathology possess a diverse expertise critical to the study of, but not limited to, transfusions and transplants, drug delivery, immunity, cancer, and blood clots. This expertise also extends to our understanding of strokes and heart attacks which are the leading cause of morbidity and mortality worldwide.
Our researchers focus on various aspects of hematopathology, including:
- platelets and blood coagulation system in bleeding disorders and cardiovascular diseases
- the role of the immune system in hematological disease
- molecular and cellular aspects of hematopoiesis
- myelodysplastic syndromes
- diagnostic research
Faculty Involved in Hematopathology Research
Dr. Branch’s research includes: (1) Investigation of the pathogenesis of HIV to identify new host cell targets for alternative therapies. (2) Projects related to the mechanism of action and replacement of intravenous immunoglobulin (IVIG). (3) The role of the signalling molecules SHP-1 and c-Src in cancers and HIV infection.
My current research areas of focus are in the following areas: (1) Transfusion support in trauma patients; (2) Transfusion support following cardiac surgery; (3) Transfusion triggers in critically ill patients; (4) Adverse reactions to blood products; (5) Transfusion-related process errors; and, (6) Management of peri-pregnancy and perioperative iron deficiency anemia.
We are interested in studying the molecular pathogenesis of multiple myeloma (MM) and identifying prognostic and predictive biomarkers in MM. We are also interested in pre-clinical evaluation of small molecules targeting various oncogenic signaling pathways as novel therapeutic strategies in MM.
Research and education focus on transfusion medicine and benign hematology (ie- adverse reactions to blood products; immunologic hematopathologies in autoimmune disease, transfusion, or transplantation; and adaptive/evolutionary blood group biology).
Lymphoma research interests
1. diagnostics, biology and immunology of lymphoma.
2. pathology review for trials
Areas of special interest/expertise: Medical Laboratory Management, Bone Marrow and Peripheral Blood Morphology, Flow Cytometry and Hemoglobinopathies.
Dr. Ghaffar is an Assistant Professor in Laboratory Medicine and Pathobiology at the University of Toronto, Adjunct Scientist in the Keenan Research Centre of the Li Ka Shing Knowledge Institute and Director of Laboratory Hematology at St. Michael's Hospital. His main areas of interest include lymphoproliferative disorders and flow cytometry.
Primary research interests include: (1) the application of molecular techniques to assist in the diagnosis and prognosis of solid and hematologic tumours; (2) understanding the genetic and epigenetic landscape of leukemias and lymphomas to determine its impact on disease pathogenesis.
Understanding how therapeutic antibodies can be used to treat autoimmune disease. We study the ability of novel monoclonal antibodies, as well as antibodies taken from the plasma of healthy blood donors (IVIg) to inhibit disease progression in autoimmunity. We also study how an antibody called "anti-D" is able to prevent haemolytic disease of the fetus and newborn.
Research and education focus on transfusion medicine and benign hematology with a special interest in pediatric transfusion issues.
My research interests are in the appropriate use of blood transfusion and improving physician education in transfusion medicine.
We investigate the role(s) of adhesion molecules (in particular the beta3 integrin & GPIb alpha complexes) involved in clot formation & their implications for hemostasis (incl. bleeding disorders) & thrombotic diseases (ie heart attack & stroke). We study allo- & autoimmune diseases related to bleeding disorders such as immune thrombocytopenia (ITP) & fetal & neonatal alloimmune thrombocytopenic purpura (FNAIT).
My research interests include transfusion medicine (blood utilization, complications), TTP/HUS, therapeutic apheresis and patient blood management.
Physician practice patterns in transfusion medicine, transfusion support of hemoglobinopathies, safety and efficacy of blood components and fractionated plasma products, transfusion practice in rural and underserviced communities.
My research interests relate to the molecular pathogenesis of hematological diseases, with a secondary interest in the cost effectiveness of diagnostic pathways.
Transfusion/platelet immunology, pathophysiology of immune thrombocytopenias, mechanism of action of IVIg/anti-D, transfusion-related acute lung injury (TRALI)
My research interests are in transfusion medicine as it relates to cardiovascular surgery and maternal fetal medicine, hematological disorders disorders of pregnancy and evidence based practise guidelines.
Dr Shek's research addresses severe hemorrhage associated with coagulopathy that requires immediate blood loss control and fluid resuscitation. His other research area explores the application of magnetoencephalography for the objective diagnosis and assessment of post traumatic stress disorder (PTSD) and mild traumatic brain injury.
Dr. Sholzberg combines her clinical, laboratory and clinical epidemiology knowledge to uniquely address her research area of focus. Dr. Sholzberg's research interests include inherited and acquired disorders of hemostasis. Currently, she is involved in the study of: prediction tools for perioperative bleeding, the appropriateness of coagulation testing and new treatments for immune thrombocytopenia.
