Research Summary

We study the biological mechanisms and evolution of how cells process information to regulate their own growth and proliferation. Using bacteria as a model organism, we aim to elucidate the detailed molecular basis for this remarkable regulatory capability, and understand the selective pressures and mechanisms that drive the evolution of signaling pathways. Our work is rooted in a desire to develop a deeper, fundamental understanding of how cells function and evolve, but it also has important medical implications since many signaling pathways in pathogenic bacteria are needed for virulence.
