We use the intracellular pathogen Shigella as a model system to study bacterial behavior in the human host. Our main interest is to learn how bacteria sense their surroundings to cause disease. We are investigating: 

• Metabolic byproducts as signals to coordinate gene expression

• The role of c-di-GMP signalling in regulating virulence

• How quorum sensing works inside a human cell

• Using intestinal enteroids ('mini-guts') to study Shigella pathogenesis
