Research
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 are released by innate immune cells including eosinophils, neutrophils, macrophages, mast cells, and epithelial cells. We are investigating alarmin cytokine secretion mechanisms from epithelial cells and have determined that SARS-CoV-2 activates the release of the alarmin cytokine TSLP. We are also evaluating the production of alarmin cytokines in nasal tissue samples from patients with asthma. Our studies are supported by a Discovery Grant from NSERC (2021-2027), and two Investigator-Initiated Externally Sponsored Grants from AstraZeneca (2020-2026).
Epidemiological studies in asthma
In collaboration with Dr. Subhabrata Moitra, Assistant Professor, Ahmedabad University, India, we are determining associations between socioeconomic factors and factors affecting allergy and asthma. We have found an influence of artificial light at night on allergic diseases, association between school absenteeism and allergic conditions among adolescents, an effect by the COVID-19 infodemic and health-related quality of life in patients with chronic respiratory diseases, and that less social deprivation is associated with a better health-related quality of life in asthma, among other studies. We also determined an association between influenza vaccination and healthcare utilization in asthma.
Teaching
I am a 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 postdoctoral fellows, graduate students, and undergraduates in benchtop experimental work as well as clinical research.
