I lecture and research around the theme of systems thinking applied to reduce environmental impact and improve sustainability, with a specialism in life cycle assessment (LCA). I coordinate and/or deliver MSc modules including LCA and Carbon Foot-printing, Resource Efficient Farm Management, Agro-Ecosystem Services and On-farm Anaerobic Digestion within the School of Natural Sciences and via distance learning for the Agri Food Training Partnership. I also deliver guest lectures on advanced courses for professionals within the International Center for Advanced Mediterranean Agronomic Studies, and am a member of the UN working group on eutrophication and acidification impact assessment methods for LCA.     

My current research is primarily focused on application of advanced LCA to calculate environmental footprints of food, energy and bio-products, with an emphasis on consequential LCA to assess the sustainability of agricultural intensification transitions and deployment of bio-economy innovations. I supervise eight PhD students and am currently principle- or co-investigator on seven UK and EU research grants, including: Bangor PI on the TRUE project promoting sustainable legume value chains across Europe; Co-I on the CLEANER COWS and SusCoRiDa projects applying consequential LCA to assess the sustainability of dairy and beef farming intensification in the UK and Costa Rica, respectively; Co-I on the Dwr-Uisce project examining environmental savings achievable in the water-energy nexus. I previously worked at Trinity College Dublin and the Environmental Protection Agency in Ireland developing methods to benchmark industrial eco-efficiency, and at the EU Joint Research Centre in Sevilla, Spain. The latter position and subsequent research grants involved review of prospective best practices from environmental “frontrunner” companies across Europe to develop guidance documents on best environmental management practice in the Retail trade, Tourism, Waste Management, Construction and Agriculture sectors. These guidance documents underpin official EC Sectoral Reference Documents and provide quantitative sustainability performance targets for companies and environmental auditors across Europe.
