Biolfilms are bacterial colonies that are attached to a surface. They grow from suspended, or planktonic, cells attaching to the surface and by cell division and movement of existing attached cells. Biofilms are found naturally in many places, including teeth (plaque), medical devices such as intravenous catheters, prosthetic heart valves, and cardiac pacemakers, in sewage pipelines, ship hulls, and many other non-human environments. Such colonies display complex spatial and temporal development patterns that are the result of both cell-cell interactions and cell-environment interactions.
We are investigating the dynamics of biofilm growth using experimental, simulation, and mathematical modeling methods. This work is a collaboration between people in both the physics and biology departments at Doane.
