Personal profile


Len Gelman, PhD, Dr. of Sciences (habilitation) joined the University of Huddersfield as a Professor, Chair in Signal Processing and Condition Monitoring and the Director of Centre for Efficiency and Performance Engineering, in 2017 from Cranfield University, where he had worked as a Professor and Chair in Vibro-Acoustical Monitoring since 2005, creating a team focused on vibro-acoustical condition monitoring of complex systems with an emphasis on their practical deployment.

During his time at Cranfield, Len has developed technologies which have been field trialled in applications ranging from aircraft engines, gearboxes, bearings, steam turbines, composite materials and centrifugal compressors. He has managed as the Principal Investigator contributions to multiple EU funded programs, UK DTI programs (4 grants), multiple EPSRC grants, Royal Society grant, USA National Academy of Sciences grant, USA National Research Council grant, and multiple industrial contracts, including multiple contracts with Rolls-Royce (6 contracts), contracts with SKF, Shell, Scotish Southern Energy (two contracts),Caterpillar (USA, two contracts), London Underground (three contracts) and Cranfield Boeing Centre of Excellence (3 contracts).

Before joining Cranfield University, Len was the Principal Investigator of USA International Science Foundation grant, USA Civilian Reserach and Development Foundation grants (two grants), USA MacArthur Foundation grant, Israel Lady Davis grant and Italian Landau Centro Volta grant.  

Len was  

•              the Technical Manager of EU Framework FP7 project Monitur 

•              the Technical Manager of EU Framework FP7 project Indgear 

•              the Technical Manager of EU Framework FP7 project PileInspect 

•              the Technical Manager of UK DTI project Sustain 

•              the Coordinator of EPSRC project

Len received Rolls-Royce engineering award for innovation in 2012, COMADIT Prize (by British Institute of NDT) in 2017 for significant contribution through reserch/development in condition monitoring, Oxford Academic Health Science Netrwork Award,  2014, William Smith Prize by UK Institution of Mechanical Engineers, 2010 and USA Navy Award, 1998.

Len is the Honorary Technical Editor for the International Journal of Condition Monitoring, the Editor-in-Chief, the International Journal of Engineering Sciences (SCMR), the Executive Director of the International Society for Condition Monitoring, the Chair of the annual International Condition Monitoring Conferences, the Honorary Co-Chair of the annual World Congresses of Engineering and a Co-Chair of the International Conference COMADEM 2019 (the University of Huddersfield).

He was the General Chair of the First World Congress on Condition Monitoring, the Chair of the Second World Congress on Engineering Asset Management and Co-Chair of the Technical Programme of the International Conference on Maintenance, Prognostic and Health Management, 2012.

Len is Co-Chair of the International Working Group of the International Committee for NDT and the Chair of the International Working Group of the European Federation of NDT.

Len has published more than 250 publications, including 17 patents and 2 book chapters and he is a co-editor of 11 books published by Springer. He is a Fellow of British Institute of NDT, a Fellow of the International Association of Engineers and a Fellow of UK Institution of Diagnostic Engineers.

Len made 40 plenary keynote presentation at major international conferences during period 1999-2018 and also made more than 100 invited lectures and seminars in the UK, USA, France, Italy, Denmark, Switzerland, Holland, India and Israel during period 1996-2018.

He was a Visiting Professor at nine Universities abroad and at Argonne National Laboratory (USA).

Len is reviewer of the following funding bodies: EPSRC, the Agency for Innovation by Science and Technology in Flanders,Belgium, German Research Foundation, Germany, Czech Science Foundation, Czech Republic, Research Grants Council, Hong Kong, China, Scottish Universities Physics Alliance, Scotland and National Research Foundation, South Africa.
