Area of Focus
- Buffalograss breeding and genetics
- Turfgrass germplasm improvement for reduced input sustainability
- Evaluate the turf potential of other native grass species
- Develop tools to improve breeding methods used in turf
Major Project Activities
My primary research objective is to develop improved buffalograss cultivars. My lab's research is focused on enhancing buffalograss performance, seed yield, sod characteristics, and stress tolerance. At a basic research level we are applying genetics and computational biology tools to advance buffalograss breeding efficiency, develop improved cultivars, and understand the genetic components contributing to turf traits and stress tolerance.
