Visiting Professor of Communications and Signal Processing

Jonathon Chambers is a widely-experienced academic leader and an expert in adaptive and blind signal processing and their application in biomedicine, communications and defence.

He has secured more than 25 research projects from industry and government to the value of £10M. He has co-authored two research monographs, one in non linear adaptive signal processing and a second in EEG signal processing, both appearing with Wiley, in 2001 and 2007, respectively; and has published approaching 500 other scientific works, including more than 150 journal papers, and has steered more than 70 researchers to PhD graduation.

Jonathon has additionally held senior academic positions at Cardiff University, Imperial College, and King's College London, and has a track record in successful strategic thinking, managing change, partnership and team-building. He has served as an Associate Editor/Senior Area Editor for IEEE journals, including IEEE Trans. Signal Processing, for more than ten years and was a Co-Technical Programme Chair for the IEEE flagship conference in Signal Processing, ICASSP, held in Prague, 2011.

He was awarded the first QinetiQ Visiting Fellowship in 2007 "for his outstanding contributions to adaptive signal processing and his contributions to QinetiQ" as a result of his successful collaboration with the signal processing team at Malvern. He also received the Teaching Excellence Award from the Department of Electronic and Electrical Engineering at Loughborough University and he was awarded one of the four Research-Informed Teaching Awards from Loughborough University in 2013. He is also a Guest Professor at Harbin Engineering University, China.

He was elected as a Fellow of the Royal Academy of Engineering in 2012 and was elevated to a Fellow of the IEEE in 2011.

Current major research interests: advanced signal processing for wireless communication systems and multimodal technologies (audio-visual) to support human interaction; signal processing for the networked battlespace.

Jonathon's education began in Singapore before continuing in Peterborough. After school he served in the Royal Navy as an artificer apprentice in action, data and control. He then studied for his first-degree in electronic and electrical engineering at the Polytechnic of Central London. He was the top graduate of the Polytechnic in 1985 and was awarded the Robert Mitchell Medal. His supervisor was Professor Gerry Cain, who first sparked his interest in the fascinating field of signal processing. After graduation, he was immediately appointed to the academic staff at the Polytechnic as a Lecturer in Signal Processing.

In 1986 he moved to Peterhouse, Cambridge University, for postgraduate research under the supervision of Professor Peter Rayner within the Department of Engineering. He also studied within the Department of Electrical and Electronic Engineering at Imperial College, under the supervision of Professor Tony Constantinides, from where he gained his PhD in adaptive signal processing in 1990. Following a year of postdoctoral research at Imperial College he joined Schlumberger Cambridge Research for three-years where he applied signal processing techniques to oilfield related problems such as measurements while drilling and volumetric analysis of multiphase flow.

In 1994 he returned to an academic career at Imperial College initially as a Lecturer in Signal Processing and then gaining promotion to a Readership in Signal Processing in 1998. Jonathon and his co-workers received the IEE Hartree Premium from the Informatics Division and the IEE Blumlein-Browne-Willans Premium from the Electronics and Communications Divisions for their research findings in adaptive signal processing.

In 2001 he was appointed to a Professorship in Signal Processing at King's College London and served as the Deputy Head of the Division of Engineering. In 2004 he was awarded a five-year Cardiff Professorial Fellowship. He initiated the Signal Separation: Theory and Engineering Relevance (SISTER) Cardiff-QinetiQ Partnership with Professor John McWhirter, FRS.

Jonathon was then delighted to join the Department of Electronic and Electrical Engineering, now the School of Electronic, Electrical and Systems Engineering, at Loughborough University in July 2007 where he led the Advanced Signal Processing Group. He also served as the Associate Dean Enterprise (ADE) and Research (ADR). He continues to work in the School as a Visiting Professor and the Director of the LSSC EPSRC/Dstl consortium.

Jonathon has served as an external MSc programme examiner for Bristol, Cambridge, Lancaster and Strathclyde Universities, and is currently serving as an external on the UG programmes for the Department of Electronica and Electrical Engineering at Imperial College. He has always enjoyed teaching and continues to deliver three modules in signal processing to undergraduate and postgraduate students. His greatest reward, however, is PhD supervision, and he wishes to acknowledge the outstanding researchers with whom he has worked and who have now moved on to many academic and industrial positions throughout the world.
