As lead analyst for SSEN DFES 2021, and project manager for the same modelling project in 2022, she has experience in leading and delivering on energy modelling across the distribution electricity networks.

Under the Open Energy Data project with UK Power Networks, she has explored the data needs for local energy planning to facilitate data centralisation and availability, as well as awareness and accessibility. She has a Masters degree in Environmental Policy from the Paris School of International Affairs.
