Research Interests

Pseudomonas syringae is a species complex of bacterial pathogens that includes the causal agents of bacterial leaf spot (BLS) on cucurbits, beet and chard. P. syringae can be seedborne, which allows for the pathogen to be introduced into new areas and spread across growing regions as infested seeds are sold and planted. One of the ways to prevent the spread of seedborne P. syringae is by developing detection methods so that the distribution of infested seeds can be prevented. My research aims to develop detection methods that not only confirm the presence of the pathogen, but determine which strain(s) of P. syringae are present. Additionally, I am interested in finding ways to distinguish between live and dead P. syringae cells on seeds, so that only seeds with live P. syringae are discarded.
