Research interests include the nutrition, health, and management of feedlot cattle.
Enhancing the nutritional and health value of animal-sourced foods for human consumption; Developing nutritional and management strategies to enhance the level of bioactive nutrients in animal-sourced foods; Examining health effects of functional/nutritionally enhanced animal-sourced foods using cell culture, animal models and clinical trials; Studying how animal-sourced foods foster human health (i.e. prevent chronic diseases and nutrient deficiencies), and their role in food security.
Improving nutrition of ruminants through study of the microbes of the rumen; increasing supply of microbial protein available to animal digestion; discovering biochemical pathways that microbes use to ferment carbohydrates in feed.
Social science and animal agriculture; policy, programs, and attitudes on animal agriculture from production through consumption; animal agriculture and climate change; animal welfare.
