Maurice Cox

Senior NPL Fellow

Dr Maurice Cox received a BSc in Applied Mathematics from City University, London, and a PhD in Numerical Analysis (spline functions) also from City University.

Maurice spent several years at the General Electric Company and has worked at NPL since 1968. He is an NPL Senior Fellow and currently a consultant to NPL where he is particularly concerned with generic approaches to the evaluation of measurement uncertainty and methods for the evaluation of interlaboratory comparison data. He has much experience in applying these approaches to diverse fields.

Since the 1990s, a main interest has been measurement uncertainty evaluation. Maurice has made major contributions to Supplements to the Guide to the expression of uncertainty in measurement (GUM) and other related guides through his membership of the Joint Committee for Guides in Metrology (JCGM). He currently leads the development of a major JCGM document concerned with the development and use of measurement models. Maurice leads a European project EMUE (2018 – 2021) concerned with establishing a large number of worked examples of measurement uncertainty evaluation to meet a widely expressed need.  The examples cover many sectors, energy, environment, quality of life, industry and society, that will support the work of the JCGM and some 10 standards committees. 

Maurice is Visiting Professor in Computational Mathematics at Kingston University, and chairs a number of national and international committees and working groups, namely, British Standards Committee SS/6 on Precision of Test Methods, and Panel SS/6/-/3 on Measurement Uncertainty, and International Standards Organization ISO/TC 69/SC 6/WG 7 on Statistical methods to support measurement uncertainty evaluation. He also chairs BIPM Director's Advisory Group on Measurement Uncertainty. Maurice is JCGM liaison for ISO/TC 69.

Maurice is a Fellow and founder member of the Institute of Mathematics and its Applications. He is also a Chartered Mathematician and a Fellow of the Royal Statistical Society.
Maurice has published some 200 papers in refereed journals.
