Research and Extension Interests
My extension programs are focused on beef cattle nutrition, production, and management from the cattlemans' pasture to the consumer's plate. I believe that great extension programs are built around the needs of the people they serve. Those needs change from year to year, so I strive to stay abreast of the most current topics, information, and concerns relative to the beef industry. Classically, I am trained both as an animal nutritionist and a meat scientist. This combination has given me a unique skill set that will hopefully allow me to bridge the gap between cattlemen and beef consumers. In the long-term I hope to be able to assist producers by providing up-to-date and comprehensive information that will decrease cost and improve efficiency in their operations. Additionally, my goal is to promote understanding and conversation between beef producers and consumers; thereby, creating a healthier environment in which Georgia's beef industry can thrive.
My research interests are have been focused on supplemental feeding strategies in young calves as well as cows, and the impact that nutrition plays in an animal's ability to reach its full genetic potential. Specifically, I have been focused on energy sources in the young calf and their effects on expression of genes that regulate intramuscular adipogenesis, lipogenesis, and fatty acid metabolism. I am also interested in integrated crop and cattle systems, specifically the utilization of crop residues as economical nutrient sources for cattle during winter months. I have no formal research appointment here at UGA, but my hope is to be able to aid in research efforts that are pertinent to my interests in any way that I can.
