Jonathan Rougier is a Reader in Statistics at the University of Bristol. He specialises in uncertainty assessment for complex systems, notably environmental systems such as climate and natural hazards. He has made several important contributions in the statistical field of computer experiments, including general approaches for representing model limitations, informal and formal approaches to model calibration and multivariate emulation for expensive models, such as climate models. Dr Rougier's recent and current collaborations include climate prediction and palaeo-climate reconstruction, ice-s...
