Research Statement
Develop and extend research based pest management information on deciduous fruit and nut crops in California. My goal is to develop Integrated Pest Management (IPM) programs which emphasize knowledge of pest and beneficial arthropod biology, and to utilize natural, cultural, biological and selective pesticide control techniques in reducing costs to farmers while maintaining crop quality and food safety.
