Sarah is a Professor in the School of Physics and Astronomy at the University of Manchester.

UK Author of over 100 refereed publications which have over 9000 citations, Sarah has won prestigious awards including a Royal Society University Research Fellowship, the Royal Astronomical Society’s Fowler Award, and grants of 3.4 million euro from the European Research Council.

Motivated by the need to reduce global greenhouse gas emissions, Sarah is also applying cosmology experience to agriculture and food research. She leads the Greenhouse Gas and Dietary choices Open source Toolkit which brings together scientists 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 engages with the public about the scientific consensus on food and climate change.

Her book, Food and Climate Change - Without the Hot Air was published in September 2020 by UIT.

In astrophysics, Sarah's research is to uncover the nature of dark energy using gravitational lensing. She was Co-Coordinator of the Weak Lensing Working Group of the Dark Energy Survey (DES) culminating in leading the first cosmology constraints from DES in 2015.
