Sarah is a Professor in the School of Physics and Astronomy at the University of Manchester. Sarah obtained a PhD from the University of Cambridge, UK in 2000 and was made Professor at the University of Manchester, UK in 2013, after research in France, Cambridge (UK) and London. Author of over 100 refereed publications which have over 9000 citations, Sarah has won prestigious awards in the UK and Europe including a Royal Society University Research Fellowship, the Royal Astronomical Society’s Fowler Award, a 1.4 Million Euro European Research Council Starting Grant, and a 2 Million Euro ERC Consolidator Grant. Most of Sarah's work so far has focused on trying to uncover the nature of dark energy using gravitational lensing, leading the first cosmology constraints from the biggest ongoing cosmological imaging survey (the Dark Energy Survey) and co-leading a consortium of hundreds of UK academics as founding Project Scientist of LSST:UK, bringing 17.7 Million pounds from the government for the UK to join this US-led astronomy project. Motivated by the need to reduce global greenhouse gas emissions, Sarah has diversified to apply cosmology experience to agriculture and food research. Sarah leads the Greenhouse Gas and Dietary choices Open source Toolkit (GGDOT) which brings data scientists together with expertise on food psychology, nutrition and life cycle analysis with the aim of reducing greenhouse gas emissions from food choices. Sarah is PI of the Take a Bite out of Climate Change project which aims to engage with the public about the scientific consensus on food and climate change. Sarah's book, Food and Climate Change - Without the Hot Air is published in September 2020 by UIT Cambridge.
