Dr Kari A. Clark received a BSc MPhys degree in Physics at the University of Warwick in 2013. He then completed two internships in the electronic engineering industry and joined the Optical Networks Group at UCL in 2014. In 2016, he completed a further nine-month internship at Microsoft Research Cambridge, applying his research in an industrial context. In 2021, he was awarded the PhD and became a Research Fellow with the TRANSNET Programme within the Optical Networks Group.

Dr Clark is currently a Royal Academy of Engineering Senior Research Fellow with the Optical Networks Group (ONG) UCL, having been awarded a 5-year Research Fellowship with the Royal Academy of Engineering in 2022. His fellowship research is to explore methods of optical clock synchronisation to achieve sub-nanosecond clock synchronisation accuracy in 6G radio access networks. Further information about Dr Clark’s fellowship can be found here. His doctoral research focussed on using central optical clock synchronization and clock phase caching to achieve sub-nanosecond clock and data recovery times in optically switched data centre networks.
