Sarah joined the GSI in 2016, prior to this she completed a Masters in System Dynamics in Norway, where her thesis focused on the role of technological change on costs to businesses (abatement costs) for greenhouse gas mitigation. This research problem was addressed through building and comparing two system dynamics models; one representing technological change, and one excluding it. Sarah also has a Masters degree in Economics, and worked for two years as a researcher at the Swiss Statistical Office, where she was part of the internal review team for the Consumer Price Index.

In addition to investigating the UK energy supply sector, Sarah's PhD also analysed the implication of certain assumptions of neoclassical economic theory on policy formation, such as the notion of equilibrium, or rational agents. She is employed as a Policy Advisor / Economist at the Federal Office for the Environment (Switzerland).
