Associate Director, McGill International TB Centre
Currently accepting graduate students and postdoctoral fellows
Research Interests
Our lab focuses on investigating the cellular and molecular mechanisms involved in the cross-talk between innate and adaptive immunity to major pulmonary infectious diseases, such as influenza and tuberculosis. Host survival during infection in vital organs, such as the lung, requires a delicate balance between host resistance, which is essential for detecting and eliminating the pathogens, and disease tolerance, which is critical in minimizing collateral tissue damage. We are also investigating how to harness the power of innate immunity in vaccine via reprogramming of hematopoietic stem cells. In summary, understanding the regulatory mechanisms involved in both host-resistance and tolerance is essential for the future development of an effective therapy or vaccine.
Research Foci
- Host defense (Resistance & Tolerance) against influenza and TB
- Hematopoietic Stem Cells in Infection and Vaccine
- Trained Innate Immunity
- Macrophage Cell Death Programs
- Metabolism in Infectious Diseases
- Eicosanoids in Infectious Diseases
