Research interests and expertise: 

The overall goal of my research program is to advance understanding of the processes underlying the introduction, evolution and spread of weeds. A sound understanding of these processes will lead to improved weed management and prevention programs. To address questions concerning weed invasions and the evolution of weed adaptations, my lab integrates genetic (molecular, population, inheritance) studies with ecological (phenotypic, spatial, demographic) studies. Our research focuses on two weed systems: (1) agricultural weeds evolving resistance to herbicides and (2) invasive weeds with horticultural origins. The two systems are not only ideal for research on processes underlying weed evolution and spread, but also include some of the worst weed problems in California. Thus, our studies have direct implications for improving the management of economically and environmentally significant plant pests in the state.

Current projects: 

  • ìEvolutionary changes in ryegrass populations since detection of glyphosate resistance and communication of resistance management strategiesî funded by USDA-NIFA-AFRI
  • ìUse of Italian Ryegrass (Lolium multiflorum) from California as a model to characterize resistance to glufosinateî funded by Bayer CropScience AG, Germany
