Research Interests

I conduct invasive species surveys throughout Utah. My research focuses on invasive species dynamics including the spread and host use of brown marmorated stink bug (Haylomorpha halys), factors affecting spotted wing drosophila (Drosophila suzukii) abundance in the Intermountain West, and using bycatch to evaluate arthropod communities in the agricultural landscapes of Utah.
