I trained as a theoretical physicist and have worked at the Institute of Food Research/Quadram Institute since 1984.
Research has centered on the application of theoretical and computational techniques in Food Materials science and Food Safety science. Food materials research has included mathematical modelling and computer simulation of macromolecular suspensions, colloids, foams, powders and grains.
Food safety research has included spatio-temporal modelling of bacterial growth, predictive microbiology and quantitative risk assessment. This research includes the development of novel computer based tools for complex systems analysis and decision support and, specifically, Bayesian Belief Network methods to encode and analyse food borne hazard domains.
Current interests include the integration of molecular data and systems biology models into risk assessments, integration of user centric information sources into risk communications and a stronger appreciation of global food chains with respect to food safety and food security. I am a STEM ambassador and have been a member of the UK Advisory Committee on Microbiological Safety of Foods since 2012.
