Career Skills and Professionalism
Research:
In my research, I work closely with plant breeders to release improved winter wheat varieties by screening breeder lines for disease resistance and by developing wheat germplasm resistant to diseases such as leaf rust, wheat soilborne mosaic virus (WSBMV), and the aphid/barley yellow dwarf complex. I also study wheat diseases, and have investigated the mechanism of resistance in wheat to WSBMV, and the effects of WSBMV, wheat streak mosaic virus, tan spot and the aphid/barley yellow dwarf complex on hard red winter wheat.
Extension:
In addition to teaching and research, I am the Extension State Specialist for small grains (primarily wheat) in Oklahoma. In this capacity, I provide extension/education materials and programs for producers and county extension educators in Oklahoma.
