My research program focuses on weather and society, especially on weather hazards, climate change impacts and adaptations, and weather-transport interactions. Some of the questions that I address include: How does weather, in combination with other variables, affect road safety in Canada? Are societal responses to weather hazards appropriate? What are the implications of climate variability and change for transportation planning and safety? What types of winter weather indices are relevant to decision making? The core of my research focuses on risk estimation and vulnerability assessment. Over time, I have begun to focus more on sustainability issues and on the challenge of creating transportation systems, and indeed cities, that are both safe and environmentally sustainable.
