Bacteria frequently occupy densely populated surface-bound communities, known as “biofilms”. It is largely unknown how bacteria organize their collective behavior inside biofilms, and how biofilms obtain their architecture. In this presentation, I will focus on how fluid physics shapes the dynamics of collective behaviors inside biofilms in geometrically complex environments. I will also introduce a new method that allows us to image all individual cells in bacterial biofilms, and show how biofilm communities avoid invasion by members of their own species and other species. This presentation will illustrate the rich interplay of bacterial cooperative behaviors in biofilm communities and physics.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
