Biography

My research addresses existing and emerging pest management issues for economically important crops in the Salinas Valley along the principles of applied insect ecology. Research projects are aimed at enhancing our understanding of biology of pest and beneficial species to develop and refine monitoring and management strategies. Major thrust is given to develop management tactics that would reduce the impact on environment and non-targets. My extension program promotes the adoption of integrated pest management driven by lab and field data that base on the occurrence and relative abundance of major pest species of vegetables and berries, and efficacy, timing and application method of insecticides on these pests. Also, my program provides diagnosis of pest problems and timely updates on the invasive pests threatening the Salinas Valley agriculture through blog, facebook, newsletter, bulletin and other media and trade Journals.
