Canada Research Chair in Barrier Immunity
Director, McGill Centre for Microbiome Research
The focus of our research is to understand how immune cells communicate with their local environment to promote protective immune responses relevant to human disease. We are particularly interested in immunity at barrier sites such as the gut, skin and lung as these tissues face the complex task of maintaining homeostasis while directly interacting with the outside world.
Ongoing studies include:
- The molecular mechanisms of CD4+ T cell differentiation following intestinal helminth infection.
- The gut-lung axis in the context of infectious disease
- Innate immune mechanisms of disease tolerance during intestinal helminth infection.
- Regulation of skin-resident IL-17-producing T cells in the context of psoriatic-like inflammation.
- The impact of the microbiome on infection and inflammatory bowel diseases.
