Profile

My research centres on developing whole-system, practical solutions that move us towards a sustainable future, particularly focussing on minimising harmful emissions and reducing waste. I work on developing and analysing sustainable processes, ranging from large-scale hydrogen production and carbon dioxide utilization to improving the sustainability of plastics, packaging, and energy-intensive foundation industries.

Quantifying environmental impacts is hugely important: it’s hard to change something for the better if you can’t measure it. I lead the UK LCA Network, which brings together academia, industry, policy makers and regulators to develop harmonised methodologies and the application of life cycle assessment in policy.

Real-world environmental challenges can’t be solved by technology alone. That’s why I lead interdisciplinary projects, such as Many Happy Returns and Buddiepack, that combine engineering with insights from psychology, sociology, linguistics, and the physical and biological sciences to understand how we can make zero-waste systems and reusable packaging mainstream. I regularly collaborate with policy makers, industry partners, the media, and the public to ensure our research makes a tangible impact.

Beyond research, I strive to develop inclusive systems and teams. Having led our departmental Athena SWAN silver award and served as Faculty Director for Women in Engineering, I am passionate about building supportive, diverse academic environments where everyone can thrive.

Originally from Teesside, I studied Chemical Engineering at Cambridge before completing my PhD here at Sheffield, along with a stint as a Visiting Professor at MIT in 2018. Outside of work, I am a former international athlete with the British Orienteering team. I love the outdoors and adventures in the Peak District, stay active coaching local athletes, mentor students on the University’s Elite Sports Performance Scheme, and serve as a Beaver Scout Leader.
 

Research interests

My research is in the development and analysis of sustainable processes and clean energy systems. My interests lie in whole systems analysis, clean energy technologies and thermochemical and electrochemical cycles for hydrogen production and carbon dioxide utilisation.

Recent projects include:

  • the EPSRC funded 4CU project, investigating utilisation of carbon dioxide to form fuel
  • the European Framework 7 HycycleS project, looking at key components for the Sulfur Iodine and Hybrid Sulphur cycles for hydrogen production
  • the KNOO (Keeping the Nuclear Option Open) project, investigating nuclear hydrogen production.
