Currently teach one undergraduate applied nutrition course in addition to helping out with other nutrition courses. In addition, will develop a graduate level course in area of expertise. Also responsible for conducting research on fetal programming in cows and also supplementation strategies for calves that can increase marbling in steers.
Area of expertise is in the field of fetal programming which is the study of the effects of maternal and environmental factors that cause alteration in fetal growth and development. I then investigate how the changes to the fetus persist into the postnatal animal and leads to physiological effects like diabetes, high blood pressure, and obesity. To accomplish my research I utilize sheep and cattle as my models. In addition to this research, I am interested in the effects of postnatal nutrition and specific nutrients on growth and marbling of calves.
