Our research centers on bacterial physiology underlying cell growth, division, and morphogenesis. Cell growth and division are critical but vulnerable processes of the bacterial life cycle. The research into these processes may reveal potential strategies for eradicating bacterial infections. In addition, we investigate proteinaceous factors that mediate host-pathogen interactions. We use experimental approaches at the interfaces of bacteriology, biochemistry, cell biology, and biophysics to tackle the following topics.

1. Metabolic regulation of bacterial growth and division
2. Cell wall synthesis and cell shape
3. Host-pathogen interactions
