I am PI and Co-I on a number of UK and international research projects in Europe, sub-Saharan Africa, and South America, including:

• RCUK-CIAT Newton Fund - tropical forage-based diets for Colombian cattle, with CIAT and Glasgow University
• CowficieNcy - an EU Marie Skłodowska-Curie RISE programme to improve cattle N use efficiency, with partners in the EU and the US
• PeaGen - a BBSRC-funded LINK project breeding and using novel peas for sustainable livestock production

I coordinate and teach MSc Livestock and Equine Nutrition modules, and tutor undergraduate the Communicating Research module. 

I am Chair in Livestock Science, the University's Director of Sustainable Farming Systems, and IBERS' Director of International Research.  My research interest is improving the use of feed nutrients for efficient livestock production: farming to make use of feeds that people cannot eat to produce foods that people can eat, while minimising the environmental impact of the processes.

• Use of forages for improved livestock production

• Short and long term effects of reducing protein intake of growing and lactating dairy cattle on immediate and subsequent productivity

• Dietary manipulation to reduce methane emissions from ruminant animals

• Sustainable intensification of forage-based production systems

• Improvement of temperate and tropical forages for improved farmer livelihoods
