Research Focus


My research focuses on the regulation of immunity from newborns to adult. I am testing the hypothesis that antigen stimuli early in life shape both developing and subsequent immune responses. I am defining key mechanisms responsible for directing the types of immune responses generated with a view to treating and preventing allergic disease. We have shown that early appropriate stimulation of the immune system results in prevention of allergic diseases in the airways and we are now studying this approach in the GI tract with a view to prevention and management of food allergies. Immunodeficiency: I have developed a cross-Canada registry for patients with immune deficiency and we have used this database to progress our understanding of why immunity fails in some patients and to develop standards for diagnosis and management of these patients in Canada.
