Areas of Research and/or Interest

Molecular genetics and functional genomics of plant pathogenic bacteria, molecular plant-microbe interactions, and management of citrus bacterial diseases.

Opportunities in the Wang Lab

Post-doctoral associate and Ph.D. student positions are available in the Wang lab to work on the interactions between Candidatus Liberibacter asiaticus, citrus and psyllid.


Microbial Defense/Host-Microbe Interactions.  This is a course for graduate students.  Principles of bacterial virulence, host defense to microbial invasion and host-microbe interactions will be examined in a context of molecular and cellular biology involving both plants and animals.  Current scientific research that incorporates these principles will also be discussed.
