Research Summary

My research focuses on basic and applied aspects of multitrophic species interactions in both natural and managed systems. I am passionate about chemical ecology at the forefront of science and my work investigates the underlying mechanisms by which plant chemical and physical traits shape multitrophic species interactions, population dynamics, and community structure of arthropods. My ongoing research can be divided into three broad areas of investigation: (i) plant-mediated trophic interactions, (ii) arthropods facilitate microbial diversity on plants, and (iii) climate change and species interaction. Through research integrating chemical assays, statistical modeling and manipulative laboratory- and field-based experiments, my work investigates the complex context-dependency of direct and indirect multi-species interactions involving plants, microbes, herbivores and predators at both population and community levels.
