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 10 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.

I am available to mentor additional students (MSc, PhD) and postdoctoral fellows, and am accepting applications from appropriate individuals.


Protein trafficking in immune cells

One of my areas of research interest is 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 are released by immune cells including eosinophils, neutrophils, macrophages, and mast cells. I have a specific interest in understanding mechanisms of cytokine and chemokine secretion from innate immune cells. This study is supported by a Discovery Grant from NSERC.

Exposure to hazardous respirable materials in the workplace

In collaboration with Dr. Lyle Melenka, Synergy Cardiac & Respiratory Care and Assistant 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, and lung cancer in these individuals. This study is supported by Lyle Melenka Professional Corporation.

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 to Dr. Nair.
