Research Interests

One key problem facing modern dairy production in both large intensive and smallholder farming systems (with either automatic milk systems or conversational parlours) is on how to better understand and deal with the apparent antagonistic relationships and trade-offs that exist among biological and environmental traits. The questions are, how to identify and utilise indicators that help to predict observed phenotypes and associations? How to effectively apply technologies and bio-models to optimise improvement strategies and the contribution of livestock to food security? Which genotypes are appropriate for which production systems? How to mitigate biological inefficiencies that lead to environmental impact?

Our team is interested in these and similar questions relating to the causes and consequences of biological and environmental efficiency or lack thereof.

My past and present research has been in the areas of bio-modeling; dairy systems; animal breeding strategies; the contribution of livestock to sustainable livelihoods and food security; and the impact of livestock genetic merit for yield and production system on economic, environmental and social elements of sustainability of dairy farming.  This has included developing and testing bio-models for detecting metabolic disorders, reproductive status and degree of mastitis in intensive high yielding systems using bio-markers measured in milk. These bio-models were included as embedded software for a commercially available dairy solution that has gone on to win three prestigious European awards. With colleagues, we have also developed models-for monitoring cow performance utilising mobile phone technology. Current work includes quantifying enteric methane and other greenhouse gases (GHG) from ruminant production systems.
