Develop a competitive and extramurally funded research program in the area of crop water use, water use efficiency, and abiotic and biotic stress resistance in major field crops in the Texas High Plains. The overall goal of my research program is to provide selection tools for breeders and geneticists and management tools for agronomists and producers, through better understanding the physiological mechanisms of crop performance under stress conditions. The major research focuses include understanding physiological and molecular mechanisms of drought tolerance, identifying plant traits conferring to stress tolerance, understanding the interactions of abiotic and biotic stresses, evaluating and developing field phenotyping tools, and developing management strategies under stress conditions. Advise graduate student research.
