Stefan Kück - TC for Photometry and Radiometry
Stefan obtained the state doctorate inphysics at the University of Hamburg (Germany) on tunable solid state lasermaterials in 2001. He joined PTB, theGerman National Metrology Institute, in 2002 and started working in the 'Laser Radiometry' team.

In 2009 he became head of the 'Optical Technologies' department and in 2013 head of the department for 'Photometry and Applied Radiometry'. Today Stefan is head of the division of 'Optics' at PTB. In addition, to being chair of EURAMET's TC for Photometry and Radiometry he joined COOMET´s TC-PR and represents PTB in the Consultative Committee of Photometry and Radiometry.

"The TC developed well in the last years due to the excellent work of my predecessors. One of the major topics during my term will be the further development of coordinated research activities within the TC to meet the upcoming challenges in the field of photometry and radiometry. The projects within the European Metrology Research Programmes are one pillar, the other maybe joint research centres. The TC should also act as a platform for discussion and planning. Besides research and innovation, there are basic duties to fulfil. I would like to improve the CMC submission process and further enhance the collaboration between all members of the TC. Therefore, it is important to consider the needs of all TC members."

Peter Whibberley - TC for Time and Frequency
Peter joined NPL, the UK National Metrology Institute, from the University of Oxford in 1984, initially working on millimetre-wavelength spectroscopy. After six years Peter moved into time and frequency metrology, working with a small team that constructed and evaluated a prototype caesium fountain primary frequency standard. From 1999, the focus of Peter's research has moved from frequency to time, and today he is the lead scientist for the operation and development of the UTC (NPL) time scale, NPL's satellite based time and frequency transfer links to other national timing centres, and its time dissemination services.

One of Peter's major research interests has been methods for time transfer over optical fibre links.Thus, he has been closely involved in the development of a commercial service to provide traceable time over fibre to the UK finance sector and other users. Peter has also participated in several EMRP joint research projects. Since 2004, Peter has played an active role in representing NPL on international committees, including EURAMET's TC-TF.

"As the new Chair of TC-TF, I would like to continue to develop the cooperation between NMIs in this field, to make the best possible use of new opportunities such as the establishment of optical fibre time and frequency links across Europe and the development of miniature optical clocks for industrial uses."
