My research interests are focused on the interactions between plants and associated microorganisms. Particularly, I am interested in infection processes, host colonization, biofilm formation, and molecular characterization of bacterial plant pathogens. I am answering research questions about the biology of pathogenic bacteria using a variety of microbiology and molecular biology techniques, as well as nanotechnology.
