Sarah combines strong mathematical and analytical skills to solve complex problems. She works extensively with Eunomia’s proprietary collection model, Hermes, and also provides modelling expertise for a range of projects.
Since joining Eunomia, Sarah has worked on a wide variety of waste modelling related work for several local authorities across England, Scotland and Wales, ranging from rural authorities, such as Cornwall and Pembrokeshire, to urban authorities, such as Derby City and several London Boroughs. Her work has primarily involved cost and performance modelling options for household waste collection services, which includes data gathering, benchmarking and waste flow modelling, as well as baseline and future options modelling, alongside delivering related workshops and presentations to officers and operational managers.
Sarah has also developed expertise in commissioning options, having modelled the financial implications of different service delivery methods for over 12 different local authorities. She also assessed the qualitative and risk impacts of the different options, enabling authorities to make decisions based on all relevant information.
In addition to her work with local authorities in the UK, Sarah has worked on multiple projects across Europe examining the effect on existing waste management services of implementing DRS systems. She has also modelled the impact of plastic reduction initiatives at a country-wide level for Greece, Indonesia and the UK.
Sarah joined Eunomia in October 2015, shortly after completing her PhD in carbon cycle modelling at the University of Bristol. She also has a first class Bachelor’s degree in Mathematics with Study in Continental Europe, for which she spent a year studying at the Université Pierre et Marie Curie in Paris.
