Research Focus

My research interests include immunologic skin diseases, medical education, and quality improvement. I have co-founded the MUHC Multi-Disciplinary Allergy–Dermatology Clinic for complex patients with chronic urticaria or mastocytosis, part of the international UCARE (Urticaria Centers of Reference and Excellence) network. I am also a member of the MUHC Centre of Excellence for Atopic Dermatitis, where I have integrated specialty clinic collaboration with the Immune Deficiency Treatment Centre to advance both patient care and clinical research.

I also hold a master’s degree in Quality Improvement from the London School of Economics. I have co-authored The Manual of Clinical Immunology & Allergy and founded AllergyIQ.ca, an innovative national learning platform designed to develop a unified Allergy–Immunology curriculum for undergraduate and postgraduate medical training across Canada. I am the Division Director for the MUHC Clinical Immunology & Allergy and McGill Clinical Immunology & Allergy.
