Food and climate change
We're bringing data scientists like me together with food and climate change experts to understand the greenhouse gas emissions of the food we eat and make these easily accessible to the public. Find out more and join for updates at GGDOT.

We're bringing food research and industry together with STFC research and facilities to solve food challenges using STFC capabilities. Sign up to the STFC Food Network+ or email email@example.com to get involved!
My background is in method development for the analysis of large cosmological datasets, specifically on gravitational lensing, to find out more about the nature of the dark energy which seems cause the mysterious accelerated expansion of the Universe. Gravitational lensing can tell us about the dark energy because it shows us the dark matter distribution. The dark matter clumps less as time passes if there is more dark energy, since the dark energy is stretching the universe out and counteracting the attraction by gravity. Compared to other cosmological probes, gravitational lensing has the greatest potential for telling us more about the dark energy. I work on galaxy shear measurement team in the Dark Energy Survey (DES), measuring shapes of 300 million galaxies across 1/8th of the sky.
Biography: Sarah is a Professor of Astrophysics in the School of Physics and Astronomy at the University of Manchester. Sarah obtained her 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 focussed 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 her research interests to applying her cosmology experience to agriculture and food research. Sarah is PI of the STFC Food Network+, which brings together food research and industry with STFC capabilities from astro, particle and nuclear physics and the UK’s largest science facilities. 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.
