My goal is to improve the efficiency of weed management systems through increased understanding of weed-crop interactions. Current research is directed towards the study of the ecology and management of three weeds: 1) nutsedges in vegetable cropping systems in the absence of methyl bromide, 2) Bengal dayflower (aka tropical spiderwort) in agronomic crops, and 3) glyphosate-resistant Palmer amaranth in agronomic crops.
