George is an applied mathematician specialising in combining mathematical modelling with experimentation to elucidate the underlying physical processes driving phenomena in complex systems. Understanding these physical processes is key when tackling a wide range of environmental and industrial challenges such as the spread of bacterial biofilms or the decontamination of hazardous materials. George has a particular focus on biological systems such as bacterial biofilms and those exhibiting collective behaviour, taking inspiration from the world around us. George's methodology aims for a holistic approach, developing simultaneously theoretical and experimental capability. Theoretically, he seeks to develop reduced mathematical models, drawing on a wide range of different mathematical techniques. Experimentation arises from a combination of collaborations with experimentalists and his own experiments, both tabletop in the laboratory and out in the field.
