My research focuses on the ecology of weeds in natural, range, and cropping systems, with an emphasis on understanding multi-trophic interactions and their implications for crops and other desirable species. Select current projects include:
- Evaluating the integration of mowing or herbicide with biological control to improve saltcedar (Tamarix spp.) management.
- Assessing the impacts of cover crop mixtures on weed and microbial communities, soil quality and weed-crop interactions in irrigated cropping systems.
- Development and evaluation of herbicide programs for weed control in chile and other irrigated crops.
- Discovering the biotic and abiotic drivers of Lehmann lovegrass (Eragrostis lehmanniana) invasion in the Chihuahuan Desert.
