Personal profile
Research
The scope is on fundamental research in the field of ruminant nutrition with focus on grazing systems and nutritional strategies, including dietary additives, to lower enteric methane emission from dairy cows. Other areas include farm-scale evaluation of mitigation strategies, improving feed efficiency, and in vitro methods to measure methane production.
Areas of expertise
- Enteric methane
- Grazing
- Environment and climate
- Feeding and nutrition
- Dairy cattle production
