I am currently working as a writer and historian of science. I am working part-time as a researcher on the Leverhulme-funded Making Climate History project based at Cambridge, where I am researching the history of climate science in the period 1965-1988. I am also working on a book on the history of computer models and the quest to save the planet. I am the author of Waters of the World (Chicago/Scribe, 2019), a history of climate science in six lives; and The Newton Papers (OUP, 2014), a history of Newton's private manuscripts. From 2016-2021 I was a trustee of the Science Museum Group. I am currently on the board of The Oxford Trust.
