2006 Ph.D. Agronomy (Minor: Statistics) – University of Wyoming
2003 M.S. Agronomy – University of Nebraska – Lincoln
2001 B.S. Agroecology – University of Wyoming


My research program focuses on developing sustainable weed management programs in agronomic crops, especially sugarbeet, winter wheat, corn, and dry beans. Recent research projects include:

  • shade avoidance responses in sugarbeet
  • long-term management of jointed goatgrass in imidazolinone-resistant (Clearfield) winter wheat
  • synergistic herbicide combinations for management of feral rye
  • new herbicide options in proso millet
  • effect of long-term glyphosate use in glyphosate-resistant (Roundup Ready) cropping systems
  • use of ethofumesate in glyphosate-resistant (Roundup Ready) sugarbeet
  • management of volunteer corn in dry beans and sugarbeet
  • economics and eco-efficiency of conventional and glyphosate-resistant (Roundup Ready) sugarbeet production systems
  • statistical modeling of herbicide absorption into plants
