Professional Responsibilities and Activities

I teach classes to undergraduate and graduate students in IPM and Crop Insect Management and undergraduate classes leading to a capstone research experience. My main research project is in livestock entomology to develop new IPM tactics including the use of repellents and attractants in a push-pull system. Other projects include collaborations on crop IPM systems and conservation of the federally endangered Salt Creek tiger beetle. International work includes consulting on curricula design and development for the Rwandan Institute for Conservation Agriculture and pest flies associated with livestock in the Philippines.
