Organisms can achieve greater actions as a group than as an individual. Population movement and territoriality in ants, birds, and wolves are examples of collective behaviors. Bacteria can also perform these behaviors. In this seminar, I will discuss how bacteria use a local sense of identity to assemble and move as a community. Our unconventional organism, Proteus mirabilis, lives in human and animal intestines and the environment. These bacteria cause disease after moving to the bladder. My research asks how an organism's identity, communication, and local environment influence collectivity.
