I am the project leader of the hard winter wheat breeding program for the High Plains and Rolling Plains of Texas. Responsibilities include management of the cultivar development project, graduate student training, and conducting research relevant to wheat genetic improvement. My current research interests are breeding for water use efficiency, introgression of forage and grain yield traits from synthetic hexaploid wheat, high throughput phenotyping for biomass production, marker assisted breeding for biotic and abiotic stress resistance, and enhanced bread-making quality.
