Professor Stephen Pierce

Electronic and Electrical Engineering

Personal statement

Professor Gareth Pierce leads a multidisciplinary team (currently 35 persons) at Strathclyde University comprising Electrical and Mechanical Engineers, Mathematicians, Physicists and Bioengineers.  He promotes collaborative research through an international network of academic partners and promotes impact though relationships with multi sector industry partners and the High Value Manufacturing Catapult Centres in the UK.  His leadership values strive to embrace a person-centred approach.  

Based in the Centre for Ultrasonic Engineering, the focus of his work is robotics and autonomous systems for inspection, including non-destructive testing and evaluation (NDT&E) for manufacture, and structural health monitoring (SHM) for asset inspection. The multidisciplinary nature of his work brings together robotics, instrumentation and interfacing, applied optics, ultrasonics, 3D metrology and machine learning based data management.  These themes resonate closely with the fundamental concepts of Industry 4. 

 Notable achievements include: 

  • Track record of multidisciplinary, industrial knowledge exchange in sectors including aerospace, nuclear, oil & gas, energy, automotive, construction and healthcare. 
  • Proven capability to migrate university research into industry
  • Managing an applied NDT technology transfer laboratory (FIRST – Facility for Innovation and Research in Structural Testing) with £11M project portfolio.
  • Managing a flexible robotic inspection facility at the Advanced Forming Research Centre – part of the UK High Value Manufacturing Catapult
  • Visiting Professorship – Production Technology Centre, Högskolan Väst, Sweden
  • John Grimwade Medal -Recipient for best paper in Insight (British Institute of Non Destructive Testing) in 2015

Teaching

I am course organiser for EE312, Instrumentation & Microcontrollers which provides a challenging mix of measurement techniques, analogue and digital electronics, combined with computer programming and interfacing.  I also contribute as project co-ordinator and assessor for EM502 Advanced Systems Engineering as well as supervising, mentoring and grading students engaged in EEE, EME and CES individual and group projects.  

Research interests

My central research interest is in robotic and automated technologies for Non-Destructive Testing & Evaluation (NDT&E) - encompassing both traditional fixed industrial robotics, and mobile vehicle technologies (including UAVs) for applications in engineering inspection. Increasingly the automation of NDT is increasingly utilised in manufacturing, this includes ultrasonic, visual and electromagnetic testing. Modern additive manufacturing techniques in particular bring new challenges to both the measurement sensors employed, and real time deployment and feedback into manufacturing processes.  

My research embraces the concepts of through-life asset management where the boundaries between NDT&E and conventional Structual Health and Condition Monitoring (SHM) are increasingly being broken down; so my research also covers wider aspects of structural integrity in sectors including aerospace, energy, oil and gas, nuclear and healthcare.   

Positioning technologies have been identified as an obstacle to the effective uptake of robotic NDT technologies, and to this end I have initiated research into a fully probabilistic basis for the challenging problems involving robot location, data fusion between multiple sensors, and mapping problems.  This naturally extends into work for full 3D metrology systems where my work is closely linked into metrology at NPL to understand how technology can be translated into the challenging manufacturing environment to support new automated systems working safely with humans.  

The Facility for Innovation and Research in Structural Testing (FIRST) established at Strathclyde six years ago, provides our researcher teams a unique range of robotic, NDT and positioning technologies to underpin this research.  This laboratory is located in room 7.14 of the Technology Innovation Centre, and is complemented by a larger flexible robotics facility at the AFRC where our research is investigated at higher TRL levels (4-6).
