Dr Ellison is Chief Metrologist and a Science Fellow at LGC, the UK National Measurement Laboratory for chemical and biological measurement, where his responsibilities include technical oversight of Statistics and of RM production at LGC’s Guildford site. Originally qualified as a chemist, his current interests include applied statistics, measurement uncertainty and reference material certification. He is a co-author of EURACHEM guides on measurement uncertainty, metrological traceability and qualitative analysis and he contributes to a range of IUPAC, ISO, CEN, BSI and other committees involving applications of statistics for measurement.

Graduated (2004) in Pharmacy-Biochemistry from the Faculty of Pharmaceutical Sciences of the University of São Paulo, master's degree (2006) and doctorate (2009) in Drugs and Medicines from the Faculty of Pharmaceutical Sciences of the University of São Paulo. He did post-doctoral internships at United States Pharmacopeia, Rockville, USA (2010) and at the University of Lisbon, Portugal (2018). He is currently a PhD professor in the Department of Pharmacy at the Faculty of Pharmaceutical Sciences at the University of São Paulo. He is also a member of ForMEQ - International Forum for Metrology and Examinology in Chemistry and of CITAC - Cooperation on International Traceability in Analytical Chemistry. He develops research, teaching and extension work in the areas of metrology and examinology in chemistry, covering the evaluation of measurement uncertainty in drug analyzes, the estimation of the risks of false decisions regarding compliance assessments, and the development of analytical procedures using the concepts of quality by analytical design (AQbD).

Ricardo Bettencourt da Silva earned his BSc in Chemistry from the Faculty of Sciences at the University of Lisbon (FCUL), his MSc in Bromatology from the Faculty of Pharmacy at the University of Lisbon, and his PhD in Analytical Chemistry – Metrology in Chemistry at FCUL. He completed the last two degrees while working full-time as an analyst in both public and private laboratories, analysing various inorganic and organic analytes in different matrices using both classical and instrumental methods. His analytical experience focused on validating measurement procedures, quality control of tests, and evaluating measurement uncertainty. In 2009, he joined the Centre for Molecular Sciences and Materials, later the Centro de Química Estrutural, at the Faculty of Sciences of the University of Lisbon, where he became a Professor of Analytical Chemistry.

His research involves developing approaches for the detailed evaluation of the uncertainty of complex measurements, examining the sources of lack of comparability of measurements across some analytical fields, evaluating the uncertainty of qualitative analysis, and creating tutorials and user-friendly software for reliable interpretation of analytical data.

Nathalie Guigues has more than 20 years of experience in the fields of water chemistry.

Her research activities concern water sampling, with the design of experimental plans to evaluate the uncertainty arising from sampling for surface waters as well as wastewaters. She is also focusing a research on developing a general framework for the validation of innovative tools. In particular, developing and testing protocols to assess the performance, under controlled and real conditions, of sensors and online analysers for water quality monitoring.

Since 2023, she is chairing the Euramet European Monitoring Network on pollution monitoring, EMN POLMO, which providesmeasurement science expertise and metrology to support the monitoring of chemicals, radionuclides, biological/microbiological and particulate pollution in air, water and soil.

She is also actively involved in standardisation at national, European and international level. Since 2023, she is the convenor of the working group WG4 of CEN TC 230 on water quality equipment (automatic samplers and on-line or in situ continuous measuring devices).
