I am a NERC-IIASA Collaborative Research Fellow at the Institute for Climate and Atmospheric Science (ICAS) in the School of Earth and Environment, University of Leeds and International Institute for Applied Systems Analysis (IIASA), Austria.

I have broad and diverse research interests. My current project will investigate how climate change affects energy supply and energy demand, and whether there are missing feedbacks between integrated assessment model derived emissions pathways and climate. I enjoy playing around with climate models to determine impact-related metrics, for example how human heat stress indices might develop under different climate change pathways. I also contributed to the Radiative Forcing Model Intercomparison Project analysis for CMIP6, and worked on the FaIR simple climate model.
