My research direction centers around the behavioral, ecological, and physiological adaptations of urban insect pests, especially understanding how these adaptations help them to thrive in the urban environment and their biological trade-offs. I am also interested in the roles of human activities and propagule pressure in invasion history of urban insect pests. Using the research findings obtained, my students and I design, evaluate, and integrate multiple management tactics to provide a system-level approach towards urban pest management. Our recent research activities focus on morphological and biological traits, insecticide resistance and its underlying mechanisms, endosymbiont roles, phylogenetics, population genetics, and environmental physiology of urban pests.
