I am the course coordinator for Inflammation MMI 436/MED 536, a combined 4th-year and graduate-level course directed towards trainees interested in the underlying mechanisms of inflammatory diseases, that is offered in the Fall semester of each year. I have been a facilitator for Discovery Learning sessions for over 15 years for 1st and 2nd year medical students enrolled at the Faculty of Medicine & Dentistry. Along with these I have been a supervisor for numerous laboratory-based courses to train undergraduates in benchtop experimental work. I am currently mentoring graduate students and postdoctoral fellows.


Cytokine trafficking in innate immune cells

We are focused on molecular and cellular mechanisms that regulate inflammatory responses in allergy, asthma, and lung diseases. Together with my trainees and collaborators, we have helped to advance our understanding of how inflammatory mediators, known as cytokines, are released by innate immune cells including eosinophils, neutrophils, macrophages, mast cells, and epithelial cells. This study is supported by a Discovery Grant from NSERC (2015-2021) and Investigator-Initiated Externally Sponsored Grants from AstraZeneca (2020-2026).

Exposure to hazardous respirable materials in the workplace

In collaboration with Dr. Lyle Melenka, Synergy Respiratory and Cardiac Care and Associate Clinical Professor at the University of Alberta, we are determining the risks of exposure of insulators to potentially hazardous respirable materials such as silica, asbestos, and other substances in the work environment. Our analysis will reveal if there is an increased risk of occupational asthma, chronic obstructive pulmonary disease, lung cancer, and cardiac disease in these individuals. This study is supported by Wellness of Workers (WoW), Local 110 Heat & Frost Insulators, and Synergy Respiratory and Cardiac Care.

Autoimmunity in severe asthma

I collaborate with Dr. Parameswaran Nair, McMaster University, and his postdoctoral fellow Dr. Manali Mukherjee, to understand autoimmunity that is associated with severe asthma. Asthma patients were found to have high levels of autoantibodies against the patients' immune cells (eosinophils, neutrophils) which appear to contribute to disease pathology. This study is supported by a CIHR grant (2016-2021) to Dr. Nair.
