Since the establishment of the CIPM MRA in 1999, the signatories have provided invaluable support by seconding personnel to the BIPM Headquarters to work as the JCRB Executive Secretary. For over two decades the secondees have ensured and promoted the efficient operation of the CIPM MRA as well as benefitting from the opportunity to expand their expertise across various domains that they may not encounter in their day-to-day roles. These include direct involvement in the coordination of international activities, the BIPM Capacity Building and Knowledge Transfer Programme, and the advancement of digital transformation in metrology. This way of working exemplifies the BIPM's dedication to supporting developing countries, which are encouraged to express their interest in future engagement opportunities.

With a Bachelor of Technology Degree in Electrical and Communication Engineering from Moi University, Ibrahim Ahmed (KEBS, Kenya) joined the Metrology Department at the Kenya Bureau of Standards as Head of the Time and Frequency Laboratory in 2004. In this capacity he provided support to the Kenyan Accreditation Service and the Southern African Development Community Accreditation Services as a technical assessor in the field of Time and Frequency metrology. Ibrahim was instrumental in establishing and maintaining the KEBS quality management system and was additionally involved in the capacity building programmes of developing NMIs from the Eastern African Region. Regarding his new position, Ibrahim said:

Dr Olav Werhahn (PTB, Germany) joined the BIPM in 2021 as the 10th Executive Secretary of the JCRB. He will return to PTB in August 2023 as Coordinator of the Innovation Cluster for Environment and Climate. Looking back at the BIPM experience, Olav explained:

The BIPM extends its best wishes to Ibrahim for success in his new role and expresses gratitude to Olav for his unwavering dedication to the benefit of the metrology community.
