My work is broadly interested in understanding climate change and its impacts. 

On the one hand, this involves statistical analyses of physical climate models to understand how anthropogenic emissions are driving global climatic changes.

On the other hand, this involves applying statistical methods from environmental economics to reveal how fluctuating climate conditions impact society. Impacts can range from those visible within the market economy (such as economic growth and inflation), to important but non-market impacts including women's welfare in developing countries and biodiversity.

I am also interested in combining these approaches to project future (and attribute historical) damages from climate change, as well as using these results to inform climate policy, for example through their combination with Integrated Assessment Models to estimate the Social Cost of Carbon.

My work is regularly reported on by international media (see publications below), and has been used to inform the work of regulatory bodies such as the European Central Bank.
