A warm welcome to our new group assistant Mr Moritz Wiegand!


Congratulations to Nia Verdon who has submitted her PhD thesis!


We are advertising an experimental postdoc position on biophysics of microbial aggregation in the context of the human gut microbiome. Please publicise it! Deadline is 22nd November.


Check out our student Patrick Sinclair's paper in Physical Review Letters presenting a model for stochastic initiation of bacterial biofilms - and a commentary on it in Nature Reviews Physics.


Congratulations to Patrick Sinclair who has successfully defended his PhD thesis!
