Welcome to the Field of Plant Pathology & Plant-Microbe Biology, which is managed by the Department of Plant Pathology & Plant-Microbe Biology at Cornell University.

From our beginnings as one of the first departments of plant pathology in the country, our tradition of excellence has centered on training graduate students for leadership in the field.  As a graduate student in our Department, you will be part of this extraordinary legacy.

I am studying gene regulation in Pseudomonas syringae pv. tomato DC3000.  Specifically, I am looking into a two-component system found to be involved in virulence.  Two-component systems are found in almost all bacteria and are used to sense changes in the environment and subsequently turn on or off genes appropriate for that environment.  Little is known about the specific two-component system I am researching, but mutants without this two-component system have been shown to be less virulent in Arabidopsis thaliana and in tomato.  I am also working on a project that uses RNA-sequencing to look at overall gene expression of Pseudomonas syringae pv. tomato DC3000 in planta
