Research Interests

plant microbe interactions

Research in my laboratory includes studies on the mechanisms controlling pathogen evolution and virulence as well as plant resistance signaling cascades. A common thread to the research that is conducted in the laboratory is the use of the Gram-negative bacterium, Pseudomonas syringae, for understanding how disease is caused on susceptible genotypes whereas defense signaling is elicited on resistant plant genotypes.
