Bacteria often live in groups, called biofilms, where they cooperate and compete with each other using a broad spectrum of interactive behaviors. These interactions are central to how bacteria evolve, and how they impact the world around them. We use tools from ecology, evolution, microscopy, and molecular biology to understand the cell-scale mechanisms and biofilm-scale consequences of bacterial social interaction.
