Microbial Interactions @ Georgia Tech
Bacteria communicate, cooperate and compete, resulting in a wide range of behaviors such as dispersal, foraging, biofilm formation, chemical warfare and quorum sensing. Microbiologists have made huge strides forward, using molecular and genomic approaches, in determining ‘how’ certain behaviors function. Despite this, answers are still lacking to some basic questions, such as ‘why’ do such behaviors evolve? Are they social? How are they maintained in natural populations? What role do they play during infection?
We are interested in how microbial cooperative behaviors and signaling systems (quorum sensing) evolve, and ultimately, the implications for virulence and disease. The main organism that we focus on is the antibiotic resistant superbug Pseudomonas aeruginosa.
