My research area bridges between transportation and environmental analysis; and my main expertise is in modelling of road transport emissions and urban air quality as well as evaluating population exposure to air pollution. I am interested in capturing the interactions between the daily activities and travel patterns of urban dwellers and the generation and dispersion of traffic emissions in urban environments. I lead an active research group focusing on modelling traffic emissions and near-road air quality as well as near-road air pollution monitoring and characterization.

Sensors installed all across Toronto to study summer heat

  An ambitious project to install 200 sensors across Toronto is underway. The study is gathering data on temperature and humidity over several summers as part of a heat study funded by the Canadian Institutes of Health Research (CIHR). The Transportation and Air Quality (TRAQ) research group, within the Department of Civil & Mineral Engineering… Read more »
