I completed my Masters and Bachelor's in theoretical physics at the University of Cambridge in 2018. Following research stays in the Environmental Science departments at Caltech and the University of Reading, I began my PhD at PIK in 2019 working on the impacts of climate change on the economy. In 2023 I successfully defended my PhD thesis and am now working as a post-doctoral researcher at PIK.

My work has drawn on empirical and modelling methods from across the disciplines of physical climate science and environmental economics to assess the costs of climate change. These include pattern-filtering and detection attribution methods to detect climatic changes in historical data and coupled physical models, as well as statistical models for identifying causal impacts of climatic changes on socio-economic outcomes such as economic growth. Currently I am interested in combining these studies to project the economic damages from future climate change and to use these results to inform climate policy, for example through estimating the Social Cost of Carbon. I also contribute to the development and management of the DOSE database of subnational economic output: https://zenodo.org/record/7573249#.ZEUEzewzZQJ
