 Yeah, my name is Kuhn Krescher and I'm a biophysicist at the Max Planck Institute for Terrestrial Microbiology in Marburg. And at the FEMS meeting next year I'll talk about how we can combine single cell level imaging of biofilm development with relatively sophisticated data analysis techniques to really learn about cell-cell interactions in biofilms and microbial communities. So basically the main question that I will be answering is what are the cell-cell interactions inside bacterial biofilms.
