From July 1st, 2017 the group moved to the Technical University of Denmark (Lyngby, Denmark).




By developing various survival strategies simultaneously, bacterial populations are well-prepared to meet harsh conditions. The Gram-positive model organism Bacillus subtilis presents a superb example how phenotypic heterogeneity influences the various developmental pathways. The development of B. subtilis biofilms requires a complex regulatory pathway, depends on cell-cell communication, and involves heterogeneous gene expression. In our group, we aim to get more insights into biofilms dynamics, i.e. what stabilize cooperation, how cheaters are excluded from the biofilms. Using experimental evolution, we aim to obtain deeper insights on the population dynamics of B. subtilis biofilms. We are also interested in the metabolic strategies during biofilm development, interspecies interactions (bacterial-bacterial and bacterial-fungal contacts), and effects of heavy metals on biofilm development and differentiation.
