I study how ecology and evolution govern the global distribution, abundance, and productivity of weeds, crops, and native plants responding to global change, with particular focus on stresses caused by competition, drought, and temperature. My work is collaborative and multidisciplinary, involving field experiments, genetic analyses, mathematics, geospatial modeling and individual based modeling.

My translational research advances fundamental theory and promotes sustainable interactions between humans and our surrounding natural, improved, and agricultural environments. It also provides excellent research opportunities for students to gain training in field and computational techniques.
