Self-introduction
I am conducting research on the virulence and biofilm formation regulation of food borne pathogens.Currently, my research involves (1) understanding the role of the ArcAB system in virulence and biofilm formation of Vibrio cholerae and (2) exploring potential antibiofilm and antivirulence compounds against different food borne pathogens.
