Areas of interest

Research has become increasingly wholistic and systems-based, addressing some of the major challenges for animal agriculture, including the large amount of methane produced by rumen microbes, the relatively low efficiency of dietary nitrogen utilization in ruminants, and the large contribution of nitrogen in ruminant livestock excreta to global nitrous oxide, ammonia, and nitrate emission inventories.  This research has included numerous long-term, multi-site, collaborative projects on reducing greenhouse gas emissions from animal agriculture and improving the efficiency of N utilization in ruminant production systems, with a focus on dietary and other management strategies for reducing methane emissions and improving the efficiency of N utilization in dairy production systems.  Chris has supervised numerous PhD students to completion across varied animal science areas.


Teaching focus is on dairy, beef and sheep production systems from a UK and global context.  Specific areas for classroom undergraduate teaching include feeding, digestion and nutrition, genetics and breeding, dairy cow transition, and environmental impacts of animal agriculture.  Field trips to local farms focus on using observations and records to evaluate management practice and improve health, welfare and sustainability.

Research projects

  • Diverse Forages Project: A multi-disciplinary (animal, plant, and soil science, agronomy, environmental and economic modelling) research on the use of legumes and multi-species swards for ruminant production systems to reduce reliance on N fertilizer and improve resilience to climate change, soil health and fertility, animal nutrition and health, and biodiversity (

  • Dairy Protein Efficiency:How Low Can We Go?:A multi-site, long-term project on ‘increasing the efficiency of protein utilization in dairy production systems’ that included a trial examining the effects of incremental reductions in dietary protein supply over multiple lactations (

  • Recent research collaborations have also included:
    • The use of novel analytical approaches and remote sensing for monitoring forage biomass and composition in situ (e.g. ‘Monitoring and prediction of pasture quality and productivity from satellites’;,
    • Diet quality, and animal health and behaviour using satellite or handheld spectral data, image analysis, and wearable devices (e.g. Hand held technologies for assessment of nutrient digestibility’;,
    • The use of high-throughput mass spectrometry analysis of milk and other biofluids for early detection of mastitis and other diseases (e.g. ‘Developing liquid AP-MALDI MS as a rapid large-scale classification method for determining farm animal health’;


Chris previously held appointments as an Associate Professor at the Ohio State University, as a Lecturer and Senior Research Fellow at the University of Reading, and as a Research Animal Scientist in the Ruminant Nutrition Laboratory of the USDA-ARS in Beltsville, MD, USA.
