William H. Darr College of Agriculture
My research efforts focus on developing covered and pasture-based finishing strategies with respect to cattle performance, nutrient management and environmental quality, and economics. Additional research efforts are to improve feed efficiency of growing cattle and mature beef cows on forage-based diets through identification of biological and genetic differences that can be used as selection criteria.

- University of Florida – Assistant Professor, April 2013 – December 2015. Appointment: 60% research, 40% extension. My research efforts focus on improving the efficiency of beef cattle production in the cow-calf enterprise through animal selection, diet manipulation, and management strategies to influence animal metabolism. These include the areas of feed intake and efficiency, nutritional effects on fetal development and subsequent performance, and management strategies to improve nutrient use efficiency of the grazing system. My extension efforts focus on educating county extension faculty and clientele on relationships of cow size and milk production on cow efficiency. This includes estimating the optimal cow size and milk production for various forage systems, and developing an excel spreadsheet to identify more efficient cows in the herd. My extension program also involves educating clientele on basic principles of nutrition and helping them to understand the influence of maternal environment on fetal programming.
- Oklahoma State University – Postdoctoral Fellow, June 2008 – March 2013. One of my research efforts focused on nutritional management of stocker cattle to influence adipose tissue development. This research determined the effect of rate of gain during the stocker phase on changes in lipogenesis and adipogenesis in different fat depots as well as changes in muscle metabolism and intercellular signaling mechanisms at different time points during the stocker and finishing phases. Additionally, I organized a research team to develop stocker cattle grazing systems that improve nitrogen, phosphorus, and water use efficiency, and reduce greenhouse gas emissions. I conducted meta-analyses of the effects of stocker production systems on subsequent feedlot performance and carcass merit, and a historical analysis of feedlot closeout data evaluating the influence of technology on feed efficiency.
I like to hunt and fish, and in general spend time out of doors. I enjoy building things and so have a word working shop in my garage that I use for home improvement projects and construct furniture.
Future Goals and Aspirations
My professional goals are to develop a strong beef cattle program at Missouri State University that will attract top students that will be future leaders in the beef industry, conduct meaningful research to advance the science, and be a source of research-based information for beef industry professionals locally and nationally. My personal goals are to build a lasting marriage relationship with my wife, and raise two sons to be strong men, good husbands and fathers, and leaders in their church and community.
Life Outside the University
I like to spend time with my family enjoying sites and events around Springfield. I am active in church serving in several different roles in previous churches prior to moving to Springfield.
