About Stephane Lajoie
Primary Academic Title
Assistant Professor of Otolaryngology-Head and Neck Surgery
Background
Stephane Lajoie obtained his Ph.D. from the Department of Pathology at McGill University, following which he trained as a postdoctoral fellow at the Cincinnati Children’s Hospital Medical Centre in the division of Immunobiology. His post-doctoral work focused on the role of complement components (C3a, C5a) in mediating Th17 immune responses underlying severe asthma pathogenesis. In 2012, he was recruited as an Assistant Scientist in the Department of Environmental Health and Engineering at the Johns Hopkins School of Public Health. In 2018, Dr. Lajoie was recruited as an Assistant Professor in the Department of Otolaryngology. Dr. Lajoie’s broad scientific interest is to understand the regulation of innate immune responses at mucosal surfaces that shape type 2 immunity.

Research Summary
Dr. Lajoie is interested in how innate immune responses regulate lung health. Innate immunity involves ancient, and well-conserved mediators, and its actions has far-reaching effects. In the lungs, innate immune responses play a critical role in response to environmental exposures such as allergen and ambient particulate matter. Dr. Lajoie's lab focuses on how these exposures can promote aberrant mucosal responses can drive the development of diseases like asthma.
