Collective behavior of bacterial communities and their resistance: Bacteria usually live in communities, which is beneficial for their survival. Many communities exist on surfaces, where the bacteria secrete extracellular polymeric substances such as proteins, polysaccharides, and extracellular DNA, which enable the bacteria to form dense aggregates. These aggregates are called biofilms. It was estimated that biofilms accounted for the majority of the bacteria in nature. In addition to being environmentally important, biofilms are also closely related to our health. For example, they are often the cause of infections. Since biofilms are highly tolerant to antimicrobials and to our immune system, those infections are often persistent and are hard to cure. Using interdisciplinary and quantitative approaches, Dr. Liu and his team focus on developing new technologies to study biofilms, investigating the underlying mechanisms and principles governing their spatiotemporal properties, and the implications for human health.
