I am an Associate Professor at the W. Maurice Young Centre for Applied Ethics and the School of Population and Public Health at the University of British Columbia, Vancouver. My current research focuses on the intersection of values and policy relevant science, especially as it relates to climate change and public health. I am the author of Philosophy and the Precautionary Principle: Science, Evidence and Environmental Policy (2015, Cambridge University Press), and am currently the primary investigator of a 5-year research project on climate change and risks of societal collapse funded by the Social Sciences and Humanities Research Council of Canada.
