I was raised on an upland livestock farm and am still a practising farmer, which gives me a first-hand insight into agricultural and environmental issues, alongside my academic perspective.

I have a broad range of research interests at the interface of agriculture and the environment. These primarily focus on livestock systems, including the challenges and opportunities to reaching Net Zero greenhouse gas emissions, management of organic resources (slurries, manures, etc.), pathogens, antibiotic resistance, and soils. Having worked on several large interdisciplinary projects, I have also developed a considerable interest in the ongoing discussions around land use (sustainable intensification, delivery of public goods, etc.). 

I have also been part of large projects researching the potential for energy savings and generation within the water sector (https://www.dwr-uisce.eu/) and small-scale hydropower plants (http://hydro-bpt.bangor.ac.uk/).

I sit on several external committees, including:

• Chair of the Agriculture Industry Climate Change Forum
• Board Member of Farming Connect
• Member of the Sustainable Innovation and Research Working Group for Hybu Cig Cymru
• Board Member of Mentera
• Bangor University representative on the Global Farm Platform group
• Member of the NFU’s Net Zero Scientific Advisory Panel
• Chair of the Carneddau Landscape Partnership (2020-2026)

I was awarded the 2023 External Award from the Farmers' Union of Wales for “services to agriculture”.

I frequently engage with industry and the media on issues related to agriculture and the environment, through the medium of Welsh and English.
