Assistant Professor and Assistant Plant Pathologist
Bacteriologist, Plant Pathologist

Ph.D. 2006, University of California, Davis, Department of Plant Pathology
B.S. in Biology 1997, University of South Carolina


Biography & Research Interests

My research program focuses on the molecular basis of the host/pathogen interactions of plant pathogenic bacteria that live in the specialized niche of the plant xylem tissue. We are focusing our efforts on understanding the strategies this group of plant pathogens employs during the initial stages of infection. In particular, I am working on Xylella fastidiosa, a serious bacterial pathogen of grapevine and citrus among other economically important hosts as well as Pantoea stewartii subsp. stewartii, an important pathogen of sweet corn and maize.
