Personal profile
Research
The main research area covers ruminant nutrition. I emphasize on feed evaluation, fiber digestion, and protein metabolism, and have experience with conducting large-scale production studies, intensive digestibility trials with measurement of methane production using multi-cannulated cows, and laboratory analysis for feed evaluation. The research also focuses on the circular perspectives of the interdisciplinary work between forage production, bio-refinery, and feed utilization in production animals.
