Background
Dr Edmond Chehura specialises in the theoretical modelling of sensor systems, in the development of practical experimentation, optical fibre grating sensors and devices, optical fibre interferometry, the development of optical instrumentation, the development of software, and in the deployment of sensor systems in industry.
He is a previous recipient of an Overseas Research Scholarship Award for his PhD, gained in 2003 at Cranfield University. He was awarded 1st prize bursary for his PhD research by Bristol Industrial Research Associates Ltd. Prior to joining Cranfield University, he gained a BSc Honours in Physics with a 1st class (University of Zimbabwe), obtained the Vice Chancellor's Award, and the Retrofit Prize (by Retrofit Ltd).
Edmond worked on the project 'Monitoring and modelling tools for the study of strain development in curing composites'', that was among a shortlist of 3 for the NPL Material Awards category of the National Measurement Awards (UK). Edmond is Co-author to REF 2014 impact case study submission: 'Optical fibre sensors: improved design of commercial superconducting magnets'. Oxford Instruments now exploits the technology in flagship commercial superconducting magnets used worldwide in high-field NMR and beam-line facilities.
He is recognised internationally in the development of fibre optic sensing systems for the process monitoring of advanced composites. He was an invited speaker to multiple international conferences in UK, France, Belgium, China, and Australia. Edmond is an invited international expert to review research grant proposals in the field of structural health monitoring of advanced composites for the Research Foundation Flanders (FWO, Belgium), an independent European Union funding agency. Edmond is a member of a global focus group created to facilitate the translation of the optical fibre sensor monitoring technology into real life implementation. Since 2020, he has been an Invited Reviewer for research grants submitted to the EPSRC. He is a reviewer of more than 16 international journals.
In 2015, he was invited by the CRC Press to contribute a book chapter in the book 'Structural Health Monitoring of Composite Structures Using Fiber Optic Methods'. Edmond is an Academic Editor for the SENSORS Journal (Hindawi), and he is a member of the technical program committee of the International Conference on Sensors Engineering and Electronics Instrumental Advances. Edmond is currently the Guest Editor leading a Special Issue on 'Fiber-Laser Sensor Systems Based on Fiber Grating Technology' for the open access SENSORS Journal (MDPI).
