I graduated from The University of Sheffield in Control Engineering with sponsorship from the UK Government’s Engineering and Science Group and the Royal Academy of Engineering. I have worked in industry on aerospace and automotive applications in the UK and Germany before taking my current post within the University Technology Centre (UTC) supported by Rolls-Royce. The UTC is embedded within the Department of Automatic Control and Systems Engineering and houses industrially relevant research in control and health monitoring systems engineering.
In my current role as Research Programme Manager and Senior Research Fellow for the UTC, I shape and co-ordinate a portfolio of industry and research council funded research, PhD projects and MSc projects aimed at delivering high quality academic and industrially exploitable research output. The projects are designed to maintain the UTC position as Rolls-Royce’s first choice for control and monitoring systems research, and to develop the Research Centre’s expertise to be positioned for industries’ future control system needs.
I am investigating a broad range of topics related to Health Management Technologies, with application to equipment health management (EHM) system design, prognostic and diagnostic algorithms, and integration of monitoring with control function for through-life adaptable machines.
Research undertaken exposes the benefit of advanced Health Monitoring through in-house development, demonstration and analysis of new technologies. Technologies explored include advances in algorithms, sensors, and the acquisition, transfer, and management of monitoring data. I have worked on developing and applying techniques directed at: modelling and forecasting degradation with Bayesian models of uncertainty; modelling faults from data and physics; performance analysis with multivariate data analysis; design of diagnostic algorithms with time-frequency signal analysis and model-based techniques; model-based design of monitoring algorithms with deployment on FPGAs, DSPs and multi-core processors; providing intelligence for adaptation to autonomous systems.
I work closely with industry on integrated project teams, demonstration engine programmes and research programmes to ensure the insertion of technology into tomorrow’s products.
