Research Interests

Ongoing research addresses the optimization of stem cell products used in hematopopietic stem cell transplantation and the translation of cell-based regenerative therapy into clinical practice. This includes analysis of how donor and stem cell product issues impact patients in Canada and research in knowledge synthesis of pre-clinical and clinical studies addressing the use of vascular progenitor cells, mesenchymal stromal cells, and extracellular vesicles in regenerative therapy.  Research in Dr. Allan’s program has been supported by CIHR, NSERC, Canadian Blood Services, The Ottawa Hospital Foundation and the Department of Medicine.

Brief Biography

Dr. Allan is a clinician-researcher with the Blood and Marrow Transplant Program at TOH, the University of Ottawa and in the Regenerative Medicine and Clinical Epidemiology Programs at The Ottawa Hospital Research Institute. He is a graduate of Queen's University and completed residency in Internal Medicine and Hematology and the University of Toronto and University of Western Ontario. As a post-MD research fellow, he studied the regenerative function of hematopoietic stem cells and he completed a clinical fellowship in blood and marrow transplantation at the Maisonneuve-Rosemont Hospital in Montreal.
