Rhys Lewis is the Director of the NPL Quantum Metrology Institute and leads the Time, Quantum & Electromagnetics (TQEM) Division. The Division covers activity in communications technologies, electromagnetic measurements, timing services, atomic clocks and quantum electronics. The Division has over 100 scientists and over 50 additional students and guest workers. Rhys has previously worked in a range of areas of NPL. He joined NPL in 2007 as an interim Division Head in the Optical Technologies & Scientific Computing team. He then became interim Group Leader for Gas Metrology & Trace Analysis, a world-leading capability at NPL. Having recruited his own replacement, Rhys took the role of interim Group Leader in the Quantum Frequency Standards Group, a technology more closely related to his scientific background. He has now moved to be responsible for the TQEM Division, which includes this Group. Rhys received a BA degree in Physics in 1980 from the University of Oxford and a DPhil degree in atomic and laser physics, also from Oxford, in 1985.
