Contact Dr 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.

Current activities

Prof. Erkoyuncu is the Director of the Through-life Engineering Services Centre. The Centre focuses on two main themes: 1) Degradation assessment, 2) Digital Service Engineering. John is a Professor of Digital Engineering. John is active with Innovate UK and EPSRC funded projects around research topics: digital twins, augmented reality, digitisation (of degradation assessment), and simulation of complex manufacturing and maintenance procedures.

John is the Course Director for the MSc in Through-life System Sustainment. This is a part-time MSc for experienced industrial professionals. The MSc focuses on the design, delivery and end of life of complex and long-life assets.

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, and improving efficiency of manufacturing and maintenance within the defence, aerospace, pharmaceutical, 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.
