Research

My research interests focus on animal nutrition and gut microbiology. Currently I am investigating:

• methods to decrease methane and nitrogen excretion from ruminants
• the role of gut protozoa in digestion in both ruminants and equines
• the structure of the bacterial population in the hindgut of horses
• the effect of probiotics on structure of the microbial populations in the gut
• the use of plant materials and probiotics to control pathogenic organisms both in animal feed and within the animal's gut
