About

Overview

Professor Rajkumar Roy joined City from Cranfield University, where he was Director of Manufacturing. Professor Roy holds a PhD in Computing from the University of Plymouth (UK) and BEng and MEng degrees in Production Engineering from Jadavpur University in India.

He started his career as an engineer at Tata Motors; pioneered research in Through-life Engineering Services (TES) with Rolls-Royce, BAE Systems, Bombardier Transportation, the Ministry of Defence and Babcock International; and established an internationally known TES Centre. Professor Roy's cost engineering and obsolescence research has transformed contemporary understanding of the engineering effort required to design, make and support high-value products, resulting in tools used by BAE Systems, Airbus, the Ministry of Defence, Rolls-Royce, and Ford Motor Company.

He is a Founding Editor-in-Chief of the Elsevier Applied Soft Computing journal and a Fellow of the CIRP (International Academy for Production Engineers), the Institute of Engineering Designers (IED), and the Higher Education Academy (HEA).

Professor Roy has advocated creative thinking in higher education and has started several new initiatives over the last twenty years. An initiative was to set up a new Centre for Competitive Creative Design (C4D), this is around £5.5m investment from HEFCE, Cranfield University, UAL and EEDA. The Centre aims to embed design thinking across enterprises to improve their creativity and make them more competitive. This is an initiative to link design with science, technology and management.
