Research Summary

The Kolter laboratory is interested in an eclectic mix of research topics that span areas of biofilm physiology, interspecies interactions, and microbial ecology and evolution. Examples of projects currently in progress are:

  • Molecular mechanisms underlying biofilm formation by Bacillus subtilis
  • Genome diversity of Bacillus subtilis
  • Microbial community dynamics in clinical and environmental settings
  • Characterization of interspecies cell-cell signaling molecules
