Assistant Professor

Randa Jabbour


My overall research goal is to utilize ecological interactions to design sustainable agricultural systems. Specifically, I study 1) pest management in cropping systems, 2) the effect of biodiversity and habitat heterogeneity on ecosystem services, and 3) the role of farmer decision-making in agricultural management, in collaboration with social scientists. Here in Wyoming, I plan to develop research projects in these areas in relevant field crop and forage systems, in collaboration with faculty and Extension professionals here at the University and with others in the region.
