Research in my laboratory is focused on ruminant livestock production, across a wide spectrum of levels of detail. Projects range from basic cellular aspects of interactions among nutrition, genetics and physiological state, all the way to regional studies of environmental impacts of different production systems.
Tools are chosen to fit the demands of each problem. Studies on adipose development may require cell isolation and characterization, culture, and biochemical assays. Studies on feed efficiency require in vivo experiments with beef cattle. Greenhouse gas inventories at the national level are conducted in silico.
Mathematical modeling is used at all levels of detail to identify critical areas of research, design appropriate experiments, and aid in interpretation of results.
