I am an Associate Professorial Research Fellow at the Grantham Research Institute on Climate Change and the Environment, at the London School of Economics and Political Science.

I work on a variety of issues in economics, with a focus on applications to environmental problems.  My current areas of research include climate change economics and policy, decision-making under uncertainty, discounting, and the political economy of policy choice.

For news about my research, media coverage, and links to articles for a general audience, please see my LSE profile page.
