Research Interest
Goss’s wilt and leaf blight, caused by Clavibacter nebraskensis, is a significant reemerging disease that poses a severe threat to global maize production. This pathogen has been widespread in recent years throughout the Midwest in the USA, in the southern regions of Texas and Louisiana, and even as far north as Manitoba and Alberta, Canada. Several plant protection organizations have classified this bacterium as a high-risk quarantine pathogen. A recent report from Mexico has raised questions about the potential origin and distribution of the pathogen, particularly from the Aztec lands where maize was domesticated through the U. S. Corn Belt.
My primary research area is centered on understanding the ecological and evolutionary dynamics of plant pathogenic bacteria and their interactions with host plants. I am particularly interested in how factors such as domestication, breeding practices, climatic changes, and evolutionary forces influence these interactions and shape pathogen populations.
Through interdisciplinary approaches integrating ecology, genetics, evolutionary biology, genomics, and bioinformatics, the research project aims to elucidate the potential origin of the pathogen and determine the functional biology behind the pathosystem interactions.
