Dr Nikolaos Boulgouris - Workshop

The National Structural Integrity Research Centre (NSIRC) was pleased to welcome a senior university lecture to an advanced non-destructive testing (NDT) workshop it organised earlier this month.

Dr Nikolaos Boulgouris, from Brunel University London, presented at the ‘Signals, systems and their applications to non-destructive testing research’ workshop held at TWI on 15 July. At the workshop Dr Boulgouris spoke to NSIRC students on the fundamentals of signal processing, including types of signals and systems, sampling issues, Fourier analysis of signals and the principles of signal processing for NDT.

The workshop also included presentations from Drs Sina Fateri and Shehan Lowe from TWI. Dr Fateri focused on ultrasonics and its applications to NDT, while Dr Lowe explained how to focus guided waves to enhance spatial resolution.

Students had the opportunity to discuss each topic with the presenters during the workshop, which proved to be a highly valuable day for all involved.

NSIRC plans to host more workshops for students in the future, to expand knowledge and bring in expert insight in the field of structural integrity.

Dr Nikolaos V. Boulgouris is a senior lecturer with the Department of Electronic and Computer Engineering of Brunel University London. He previously served as a lecturer and a senior lecturer at King's College London, and prior to that was a post-doctoral fellow with the Department of Electrical and Computer Engineering of the University of Toronto, Canada. Dr Boulgouris has published more than 90 papers in international journals and conferences and his papers have been cited widely in papers by other researchers who work in the same area of research. He was principal investigator for the UK group in the EC-funded project ACTIBIO and also the PI or co-I for a number of PhD projects funded by TWI. He is an elected member of the IEEE IVMSP Technical Committee (IVMSP - TC) and is a Senior Member of the IEEE.


Dr Sina Fateri completed his MSc in wireless communications engineering with distinction from Brunel University London in 2011. He then began a role as teaching assistant in the Wireless Communication and Signal Processing Laboratories of Brunel University London. He started his PhD in advanced signal processing at Brunel University London, based in Plant Integrity Ltd, in 2012. His work addressed signal interpretation challenges in ultrasonic guided wave inspections. During his studentship he published 15 papers, including conference and peer-reviewed journals, and served as a reviewer for the Journal of Non-Destructive Testing and Evaluation and the journal of the British Institute of Non-Destructive Testing, Insight. He completed his PhD in December 2015 and is now a project leader in Plant Integrity, performing critical work and automated analysis of large ultrasonic data sets for EDF Energy and satisfying EDF Energy’s safety requirement for on-going monitoring of two nuclear power stations in the north of England (Heysham and Hartlepool reactors).


Dr Shehan Lowe received the PhD degree from the Electrical and Computer Engineering Department, Brunel University, London in 2016. He commenced his career in the field of non-destructive testing by joining TWI’s Integrity Management Group in Cambridge as a research engineer in 2012. He is currently working as a research fellow at the Brunel Innovation Centre, Cambridge. His research is focused on finite element methods and signal processing on ultrasonic guided waves (UGW). His research interests are to develop UGW sensors to achieve higher flaw sensitivity, UGW energy-focusing and ultrasonic cleaning using high-power transducers. He has published over ten research articles in national and international journals and conferences. Since 2014 he has served as a reviewer for the IEEE Sensors Journal, NDT&E and Insight journal.
