My research interest is in air pollution and related health effects on children. Currently I am working on the following projects: 1. Studying particulate matter collected from the air and its effects on cells exposed to it. 2. Mapping the distribution of children's disease and industrial air pollutants in Canada. 3. Understanding the role of air pollutants from traffic and industry on premature births. 4. Understanding how particulate matter alters our defense mechanisms is predisposing us to infections like tuberculosis. 5. Understanding how the interaction of multiple environmental variables impact on children's health.
