Contact Professor John Ahmet Erkoyuncu
Areas of expertise
- Computing, Simulation & Modelling
- Throughlife Engineering Services
Prof. Erkoyuncu previously worked as a Senior Lecturer in Digital Service Engineering. His research focused on: 1) augmented reality applications in manufacturing and maintenance and 2) modelling maintenance requirements.
Prior to becoming a Senior Lecturer and Lecturer, as Research Fellow, John was based at Rolls-Royce, Derby. In this role he developed a software tool to trade-off the design requirements (e.g. unit cost, emission, noise). Prof. Erkoyuncu was also involved in an EU funded infrastructure project on visualisation. His responsibility focused on implementing augmented reality.
John’s PhD focused on how to quantify the impact
of uncertainty when estimating the cost of maintenance. His PhD was conducted
in collaboration with BAE Systems, Rolls-Royce and MoD. The project focused on
the bidding stage of availability based contracts.
Prof. Erkoyuncu is Head of the Centre for Digital Engineering and Manufacturing. In parallel to his research interests, the Centre focuses on: 1) digitalisation of manufacturing processes, 2) complex systems and optimisation, 3) digital twins and AI, and 4) virtual and augmented reality. John is a Professor of Digital Engineering. John is active with Innovate UK and EPSRC funded projects.
Prof. Erkoyuncu is currently co-supervising eight PhD projects; which are all co-funded by industry. The projects are focused on enhancing
predictability of complex maintenance, improving efficiency of
manufacturing and maintenance within the defence, aerospace, pharmaceutical, rail, health and automotive sectors. John is a Chartered Engineer, Fellow of the Higher Education Academy, a former Chair of the CIRP Research Affiliates (2018-2019) and a Member
of IET. He is currently the co-chair of the Through-life Engineering Services Council. Professor Erkoyuncu is an Associate Member of CIRP.
