I specialize in research on the human dimensions of environmental change, with particular attention to the relationship between environment and human migration; community adaptation to climatic variability and change; and, fostering citizen participation in environmental science. As a former Canadian foreign service officer, I worked at Canadian diplomatic missions in Belgrade, Hong Kong, New Delhi, Seattle and Vienna. In recent years I have advised UN agencies, the World Bank, and governments in Canada, the US, and Europe on issues related to climate change, migration, and security. I am currently a Coordinating Lead Author for the Intergovernmental Panel on Climate Change’s working group on impacts, vulnerability and adaptation.
