Responsibilities and Interests:

My program focuses on the fundamental and applied arenas of genetics, ecology, and physiology in introduced and native grass species aimed at enhancing turf quality, seed yield, persistence, disease resistance, and tolerance to salinity, drought, and extreme temperatures (both heat and cold) using traditional, molecular, and genomic approaches. In addition, my program performs a range of genomic investigations on the reproductive biology of these grasses including such systems as apomixis and dioecy.
