Chemical ecology of pathogen-host-vector interactions
The spread of insect-borne diseases is mediated by complex interactions among pathogens, their hosts, and insect vectors, but our understanding of the physiological and ecological mechanisms governing these interactions is limited, despite clear significance for agriculture, ecology, and human health. Chemistry invariably plays a central role in mediating such interactions; yet, relatively little work to date has addressed the chemical ecology of insect-vectored diseases. My research focuses on investigating the biochemical mechanisms mediating plant pathogen transmission in complex ecological settings and their implications for host plant interactions with other organisms. We are particularly interested in studying how vector-borne pathogens of plants and animals might evolve to alter traits of their hosts in ways that influence the frequency and nature of interactions between hosts and insect vectors. We also explore how pathogen-induced phenotypic shifts affect interactions between hosts and other (vector or non-vector) organisms in ways that modify food webs, alter the outcome of competitive interactions, and influence flows of energy and nutrients.
