DESCRIPTION:Collective behaviour is everywhere in nature\, from the flocki
 ng of birds to the schooling of fish. In this talk\, I will investigate tw
 o such phenomena in more detail through the use of mathematical models. A 
 bacterial biofilm is a consortium of microorganisms embedded in an extra-c
 ellular matrix. They are ubiquitous in nature\, being found everywhere fro
 m on stagnant pools of water to plaque on teeth. I will present a mathemat
 ical model developed in order to understand the growth of a biofilm in con
 finement e.g. on the surface of a catheter. Secondly I will introduce the 
 marine acoel Symsagittifera roscoffensis and in particular the collective 
 motion observed as the density of worms increases.
