Academic Profile

Research Interests

My research program involves evaluating the influence of forage quality and grazing management on beef nutrition and production in the southeast.  Through the implementation of a number of applied research evaluation methods, my current program has a strong focus on the utilization of alfalfa interseeded into bermudagrass and the associated effects on beef nutrition.  Working at the animal-plant interface, I conduct small and large scale plot studies followed by large-scale grazing evaluations on predominately perennial warm season grass based pastures.  I also work closely with colleagues within and across departments at UGA, USDA-ARS, and at various southeastern universities to develop strong teams focused on a systems approach to answering complex beef-forage related questions.  Additional associated work include evaluations of annual forage species, effects of yield and harvest timing on forage quality, effects of harvest method and prolonged storage on nutritive value of forage products, and the associated effects on beef cattle nutrition.  The main objective of my program is focused on improving beef nutrition and forage quality and utilization while extending the grazing season.

Extension Interests

The focus of my Extension program is on improving beef cattle production and efficiency within beef cattle management systems of the southeast.  My goal is to provide education and guidance that leads to better decision making associated with forage based livestock production, specifically as it relates to forage management, beef nutrition, and feeding strategies.

Program Objective

The overall objective of my program is to streamline research and extension efforts through applied research evaluations that provide timely and applicable management strategies to the end-user; Resulting in improved beef nutrition and grazing management and extended grazing across the Southeast.
