My research interests are in understanding the abiotic and biotic factors that drive the spatial and temporal dynamics of insect populations in relation to economically important traits and agricultural practices. My work encompasses everything from investigating immediate pest management problems of local, regional, national, or international scale, to advancing basic understanding of fundamental concepts in biology and related sciences, to working toward solutions for big-picture issues related to sustainable agricultural production and feeding the growing population. Applied research projects funded by the USDA, state, and national commodity groups aim at improving our understanding of biology, ecology and integrated pest management of insect pests of cotton, soybean, sorghum and peanut. A large component of my current research program is also focused on better understanding vector-virus interactions responsible for transmission of plant pathogens, including genetic mechanisms of vector-transmission in insect and pathogen populations, how population-level processes shape viral genetic diversity and evolution, and the epidemiological significance of these interactions. My lab researches thrips transmitted tospoviruses, aphid transmitted Cotton leafroll dwarf virus, and whitefly transmitted begomoviruses. Currently, my lab is investigating the effect of whitefly transmission on evolution of East African cassava mosaic virus, African cassava mosaic virus, Tomato mottle virus and Tomato yellow leaf curl virus to better understand the impact of whitefly transmission on begomovirus genetic diversity and evolution. This work is being conducted in collaboration with NCSU, Rutgers, NC A&T, Biosciences Eastern and Central Africa – International Livestock Research Institute Hub in Nairobi, Kenya and the Mikocheni Agricultural Research Institute, in Tanzania. I also have an interest in using population genetics as a tool to better understand the development and spread of economically important traits, and have an ongoing project examining variation in population genetic structuring of a thrips pest of cotton in relation to variation in insecticide resistance status.
