Giuseppe received his degree from the Politecnico di Torino (Italy) and his PhD degree from the Optoelectronics Research Centre (ORC) of the University of Southampton. He joined the Time & Frequency Group at NPL in 2002, where he initially worked on cryogenic sapphire oscillators and frequency synthesis for the NPL primary frequency standards. He then moved to the optical frequency comb and frequency transfer areas, developing new techniques for accurate time and frequency dissemination via optical fibres as well as fibre-based frequency stabilization techniques.
At present he is working as a Senior Research Scientist at NPL and he leads the research on novel applications of frequency dissemination techniques over optical fibre links.
Areas of interest
Giuseppe Marra is currently working on detecting earthquakes using optical fibre links. His work on fibre-based seismic detection was published in Science in June 2018.
