  • 2014 - The formation of bacterial biofilms at surfaces is a significant problem in many industries and medicine. Biofilms often lead to the failure of processes such as water management, food production and medical implant techniques. At Swansea University we are developing novel methods that disrupt biofilm formation at surfaces and are looking to recruit a doctoral student to undertake a research project optimising biofilm control methods. The research of the project will be in collaboration with industry as part of an EngD sponsored by the EPSRC. The student will use advanced surface and particle characterisation techniques alongside flow chamber hydrodynamic shear assaysto study the formation and control of industrially relevant biofilms. The work wil ltake place within the Multidisciplinary Nanotechnology Centre and the Centre for Nano-Health at Swansea as part of the COATED Centre for Doctoral Training.
