Assistant Scientist



My primary research interests include characterization of host-pathogen interactions and understanding molecular physiology of biotic (and abiotic) stress tolerance in crops. As a member of Profs. Jeff Jones’ and Frank White’s research programs, we seek to functionally characterize Ca. Liberibacter asiaticus and Ca. L. solanacearum effectors using transgenic approaches. I am also interested in developing marker-free gene and base editing protocols for Clavibacter nebraskensis.
