I conduct fundamental and applied research on the biological and environmental processes that influence the population dynamics of plant-associated arthropods in tropical and subtropical fruit crop systems. My work focuses on two main areas: biological control and the ecology and management of invasive insects and mites. My research examines multi-trophic interactions among host plants, pest arthropods, and natural enemies and how these interactions affect biological control outcomes. I have a particular interest in the ecology and management of invasive/pest arthropods, especially those that vector plant pathogens.
