Electron tomography of prokaryotic cell surfaces


Personal group site

Our laboratory uses electron tomography, combined with several structural and cell biology techniques, to study cell surfaces of prokaryotes at the atomic level. Surface molecules mediate cellular interactions with the environment and play important roles in key processes including cell adhesion, biofilm formation and antibiotic tolerance in pathogenic bacteria.

Our research aims to push the boundaries of cellular structural biology, with technical developments aimed at identifying molecules on cell surfaces, and resolving their high-resolution details in prokaryotic cells. While structural biology of many cell surface molecules reveals fundamental information about bacteria and archaea, our work has clear biomedical relevance, for example surface molecules allow pathogenic bacteria such as P. aeruginosa to evade antibiotics with biofilm formation.
