Research Interests

The main interest of my laboratory is to study of molecular mechanisms that govern plant immunity and susceptibility to bacterial pathogens. On the plant side, we use molecular biology, functional genomics and proteomics approaches to dissect recognition events and signal transduction pathways that mediate immunity. On the bacterial side, we apply genetic and biochemical strategies to unveil the mode of action of bacterial virulence factors that manipulate host functions. Our investigation has a direct impact on agriculture by providing targets and biotechnological strategies for the development of disease control against economically important pathogens.
