Research Interests

I am responsible for leadership of entomology extension programming on a statewide basis, with special emphasis on the development of integrated pest management (IPM) programs. I serve as liaison between the University and grower and public groups in Arizona and strive to enhance collaboration in IPM between the diverse pest biology research programs underway in the State. Additionally, I direct the UA Extension Arthropod Resistance Management Laboratory, which addresses monitoring and management of resistance in arthropod pests.
