My research examines air pollution using advanced instrumentation and data mining. Our goal is to make key connections between emissions of pollutants, the quality and composition of urban air, and the impacts on human health and the environment. Focus areas include traffic related air pollution, Identifying the sources of pollution, development of inexpensive sensors, and understanding how the sources and composition of particulate matters influences its potential to induce oxidative stress. Most of my research is executed through the Southern Ontario Centre for Atmospheric Aerosol Research (SOCAAR). SOCAAR is an interdisciplinary centre for the study of air quality, with a focus on how aerosol particles impact human health and the environment.
