Expert in Gas Metrology
Back to all chairs and co-chairs

As an expert in Gas Metrology, I oversee the infrastructure component of the WMO Global Atmosphere Programme, coordinating quality, traceability, and calibration within the WMO Standing Committee on Measurements, Instrumentation, and Traceability. My academic background includes an MSc in Chemistry from the University of Barcelona (2000), with additional certifications in Quality Management from the Association of Chemists of Catalonia, Linde European Leadership, and UKAS Uncertainty of Measurement. I started my career at Linde Gas’ ISO 17025-accredited specialty gases laboratory, gaining expertise in gas analysis techniques like Spectroscopy and Gas Chromatography, and became proficient in validating reference standards. Later, I moved to instrument manufacturing, contributing to the testing and development of Non-dispersive Infrared Sensors, Tunable Diode Laser Spectroscopes, and Gas Chromatographers. In 2014, I joined the National Physical Laboratory (NPL) in London, focusing on Primary Reference Materials in compliance with ISO 6142. At NPL, I led initiatives in Volatile Organic Compounds (VOC) and Breath Analysis, contributing to publications in leading journals. My work included international projects like the EMPIR 16ENG05 on Biomethane and other key intercomparisons, establishing NPL’s global leadership. Since 2022, I’ve held a joint position at WMO, working on QA/QC, Capacity Development, Data Management, and Network Design. I’ve also organized training workshops and intercomparison campaigns, notably in Cairo (2023) and Santa Maria (2024). In 2023, I joined the CIPM Task Group on Climate Change, acting as a WMO focal point. My goals are to ensure network compatibility, maintain data integrity, and expand the GAW network strategically.
