The goal of my research program is to develop multi-tactic approaches to weed management that are appropriate for agricultural ecosystems in the southwestern United States and that are built on sound knowledge of weed ecology/biology. Many agricultural weeds complete a life cycle in one year. For these weeds, reserves of seeds in soil (i.e., seedbanks) are critical to long-term population growth rates. Accordingly, my research aims to develop novel management tactics that directly target weed seedbanks.

Previous projects have clarified weed seed defenses, seed-predator interactions and abiotic factors that influence weed seed fate. Currently, my research group is conducting field and laboratory experiments on seed mortality and seedbank dynamics of agricultural weeds of southern New Mexico. In addition to enhancing knowledge of weed seed survival, I hope to provide farmers the information needed to deplete weed seedbanks through natural ecological processes including seed decay and fatal germination.

Additional projects in my laboratory focus on the development of applicable management strategies for weeds in New Mexico crops including chile pepper and canola. The general approach is to manage weeds using combinations of herbicides and cultural practices. Through diversification, my goal is to make weed management programs more reliable and more cost-effective in the long-term.
