Expertise. Understanding bacterial multicellular communities, such as biofilms. This field is highly significant from clinical, agricultural and ecological perspectives, e.g, biofilms formed by various pathogens play a critical role in device-related infections, dental infections, acute septic arthritis and plant diseases.  On the same time, biofilms formed by beneficial bacteria can also be highly beneficial for maintaining the diversity of natural habitats.
