Nouveau secrétaire exécutif du JCRB

On 10 January 2019, Dr Sten Bergstrand, on a two-year secondment from RISE (Sweden), took over as Executive Secretary of the Joint Committee of the Regional Metrology Organizations and the BIPM (JCRB Executive Secretary). Sten takes over from Nikita Zviagin who has returned to VNIIM (St Petersburg, Russian Federation), having completed a two-year secondment at the BIPM.

Sten, the ninth seconded Executive Secretary of the JCRB, has a broad background from geophysical geodesy and length metrology. Until taking up his role at the BIPM he was leading RISE's group in dimension and positioning metrology, with particular interest in GNSS applications and local tie measurements of co-located techniques at space geodetic stations. He has published papers on GNSS monument stability and deformations of geodetic telescopes and was the Swedish representative to EURAMET technical committee for length.

The primary role of the JCRB is to coordinate the activities among the RMOs in establishing confidence for the recognition of calibration and measurement certificates, according to the terms of the CIPM Mutual Recognition Arrangement (CIPM MRA). The JCRB, which is chaired by the Director of the BIPM, is supported by Executive Secretaries seconded from the NMIs from across the globe. This approach strengthens the links between the BIPM and the RMOs, helps transfer knowledge to the RMOs and brings recent "front line" experience to the BIPM. Previous JCRB Executive Secretaries were: Dr Angela Samuel (NMIA, Australia), Dr Ismael Castelazo (CENAM, Mexico), Dr Pedro Espina (NIST, USA), Mr Luis Mussio (LATU, Uruguay), Mr Ömer Altan, (UME, Turkey), Mr Chingis Kuanbayev (KazinMetr, Kazakhstan) and Dr Douglas Olson (NIST, USA).
