My research interests focus on improving the efficiency of livestock production to reduce its environmental impact. Current interests include:

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

Metabolomic analysis of biological fluids for diagnosis of dairy animal nutrient use efficiency and welfare
