Research and Extension

My research addresses existing, emerging and invasive pest management issues of turfgrass and ornamentals 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 principles driven by lab and field studies.
