We are interested in understanding the factors driving the emergence of new diseases by studying different aspects of pathogen and disease ecology. We take advantage of approaches used in ecology, molecular ecology and evolutionary biology to infer the history of epidemics and potential trajectories of emerging pathogens.
We are interested in what drives Xylella fastidiosa jumps from one host plant species to another, and how the pathogen changes after bottlenecks (introductions into new regions). We have also been pursuing questions related to X. fastidiosa adaptations to climate.
We aim to understand how vectors acquire the pathogen from an infected host and later inoculate it into a susceptible one. It is also important to identify what organism is the vector and the relationships between vector and pathogen taxa. We also study how biotic and abiotic factors affect pathogen transmission rates.
