My research program focuses on understanding the biology and ecology of turfgrass insect populations to improve current management practices and develop novel, more sustainable management and monitoring programs.  Given the heavy reliance on chemical controls in many managed turfgrass systems, little is known about the ecology of many soil arthropod pests and communities.  I have used the annual bluegrass weevil (Listronotus maculicollis Kirby), a severe and widespread pest of intensely managed turfgrass, as a model to explore many questions that I have regarding insect ecology.
