Research Statement
I am a climate scientist focused on quantifying the impacts of climate change on natural and human systems. My research assesses real-world consequences across diverse applications, from extreme heat constraints on major sporting tournaments to climate-driven impacts on agriculture, ecosystems, and infrastructure. It draws on observed and modelled climate data, alongside a range of process-based impact models.
