Research Overview
I conduct basic and applied research on important thrips, whitefly, and aphid transmitted plant viruses (Tospoviruses, Geminiviruses, and Potyviruses) affecting several crops in Georgia and in Southeastern United States. My goal is to understand these viral pathosystems at micro and macro levels. My lab is currently involved in studying the process of virus-transmission by vectors, component (vector-virus-host plant) interactions, and dissecting the various factors that mediate these interactions by employing behavioral, biochemical, serological, and molecular approaches. My research also aims to understand the various factors that influence the ecology and epidemiology of these insect-transmitted viruses.
