I coordinate the TAES sorghum breeding program at College Station, Texas. Our long-range goals are to enhance the productivity and profitability of sorghum production systems. The sorghum breeding program is used as a mechanism to develop and release sorghum germplasm to meet this goal. In addition to the release of improved sorghum genotypes, my research interests focus on the genetic and molecular genetic inheritance of disease resistance, grain quality and agronomic productivity and adaptability. The research provides opportunities for graduate student training in fundamental and applied aspects of plant improvement.
