Polina Bayvel portrait

TRANSNET Principal Investigator

BSc(Eng), PhD, CBE, FRS, FREng, FIEEE, FOSA, FInstP, HonFIET

Professor Polina Bayvel is the Head of the Optical Networks Group at UCL which she also set up in 1994. Her research interests are in the area of optical communications and include wavelength-routed optical networks, high-speed optical transmission, and the study and mitigation of fibre nonlinearities. She was one of the first to show the feasibility of using the wavelength domain for routing in optical networks, and designed wavelength-selective devices needed for their characterisation and implementation. More recently she has focused on the study of capacity limits in nonlinear optical networks and optical networks for the cloud. She has authored or co-authored more than 350 refereed journal and conference papers.

Polina Bayvel received her BSc (Eng) and PhD degrees in Electronic & Electrical Engineering from University of London, UK, in 1986 and 1990, respectively. In 1990, she was with the Fiber Optics Laboratory, General Physics Institute, Moscow (formerly USSR, now Russian Academy of Sciences), under the Royal Society Postdoctoral Exchange Fellowship. She was a Principal Systems Engineer with STC Submarine Systems Ltd, London, UK, and Nortel Networks (Harlow, UK, and Ottawa, ON, Canada), where she was involved in the design and planning of optical fibre transmission networks. During 1994-2004, she held a Royal Society University Research Fellowship at University College London (UCL), and in 2002, she was appointed to a Chair in Optical Communications and Networks.

Professor Bayvel is a Fellow of the Royal Society (FRS), Royal Academy of Engineering (FREng), Optical Society of America (FOSA), Institute of Electronic & Electrical Engineers (FIEEE), the UK Institute of Physics (IoP), and the Institute of Engineering and Technology (IET). She was the recipient of the Royal Society Wolfson Research Merit Award (2007-2012), 2013 IEEE Photonics Society Engineering Achievement Award, 2014 Royal Society Clifford Patterson Prize Lecture and Medal and in 2015 together with 5 members of her group, received the Royal Academy of Engineering Colin Campbell Mitchell Award for 'pioneering contributions to optical communications technology'. She was the PI of the UK EPSRC Programme Grant UNLOC (2012-2018), focused on unlocking - and maximising - the capacity of optical communications., and now leads the TRANSNET Programme Grant (2018-2024).

She was awarded CBE (Commander of the Order of the British Empire) in the 2017 New Year's Honours List for services to engineering.
