Expert Witness

Barrie Wells, PhD, FRSS, our co-founder, has been deployed as expert witness in two high-profile cases involving the application of standards to the construction industry where breaches of standards' provisions were claimed. With a first degree in mathematics and statistics, a PhD in statistical mechanics and over 40 years consulting for extraction, construction and infrastructure companies, he is particularly well placed to bring together the practical and theoretical aspects of statistics that have a bearing on such cases. Having played a significant role in the setting up of standards bodies in the oil industry and latterly been invited as an Expert to contribute to the ISO technical committee on Sampling procedures for inspection by attributes / Sampling procedures for inspection by variables (SO/DIS 3951), Dr. Wells' knowledge of standards from both sides, specification and application, has proven invaluable to defendants in both litigation and arbitration.

Dr. Wells maintains an active interest in statistics, keeping up to date with latest developments. He serves on the committee of the Machine Learning Special Interest Group of the PESGB, is a member of the Applied Petrography Group of the British Geological Society and he continues to teach part-time. He has been a visiting lecturer at Nottingham University and the University of Liverpool as well as giving post-experience courses to companies, governments and individuals in 25 countries.
