Bacterial Biofilms

Bacterial Biofilms

Prof. Dr. Knut Drescher


Research area

The lab focuses on understanding collective bacterial behaviors, using biofilm formation and swarming as model systems. Bacterial biofilms are surface-associated bacterial communities that are held together by an extracellular matrix. Cells within these communities are highly resistant to antibiotics and display strong phenotypic heterogeneity. Using microscopy, molecular biology techniques, and mathematical modeling, we study how bacteria form these complex multicellular biofilm communities, and how biofilms affect bacterial ecology.
