I study the ecology of insect vectors and how their interactions with biotic and abiotic environmental variables affect epidemiology of related vector-borne diseases. My interdisciplinary questions are set to improve our knowledge of pathogen-vector-plant interactions at different biological levels. A clear understanding of such interactions is a critical step towards developing integrated, sustainable, and environmentally sound pest management strategies.
