DESCRIPTION:Biofilms are slimy colonies of bacteria that have settled on a
  fluid-solid interface. They are ubiquitous and often undesirable and pres
 ent numerous challenges in medicine and industry. They consist of bacteria
 \, polymeric substances and water to form a porous structure that changes 
 as the biofilm grows and matures. In this talk\, mathematical models will 
 be presented to describe biofilm growth as an expanding viscous fluid. The
  talk will broadly be in two parts. Firstly\, a model for the early stages
  of biofilm development using thin-film approaches\, where Depending on th
 e strength of interaction between bacteria and the substratum two limits n
 aturally arise. Secondly\, a model that uses ideas from mixture theory to 
 describe mature biofilm development\, enabling prediction of fluid flow re
 gimes within the biofilm structure.\n
