Peter Whibberley

Senior Research Scientist

Peter Whibberley is a Senior Research Scientist in the National Time Scale group. He is responsible for the maintenance and operation of the national time scale UTC(NPL), including the GNSS and two-way satellite time and frequency transfer (TWSTFT) links, and the time dissemination services. In recent years Peter has investigated methods for time transfer over optical fibre networks, including proof-of-concept trials that led to the development of the NPLTime® service for the financial sector and other users. Between 2017 and 2021, Peter was the Chair of the EURAMET Technical Committee for Time and Frequency (TC-TF), and he also represents NPL on ITU-R Working Party 7A, covering international coordination of broadcast standard-frequency and time signals.

Peter joined NPL after graduating from the University of Oxford, working initially on millimetre-wavelength spectroscopy for the JET nuclear fusion experiment and to characterise high-temperature superconductors. After moving into time and frequency metrology, Peter started the development at NPL of a caesium fountain primary frequency standard, initially in collaboration with the University of Oxford, and worked on the construction and evaluation of the prototype fountain for the following 10 years. Peter then took over responsibility for the operation and development of NPL's time scale and time transfer systems. Peter has given a number of radio and television interviews and briefings to journalists, many of which were about the future of the leap second in UTC.

Peter is a Member of the Institute of Physics (MInstP) and a Chartered Physicist (CPhys).
