Current activities

Head of Centre for Propulsion and Thermal Power Engineering;

Propulsion is around 70 staff strong (including visiting academics) and one of the largest research and education activities within SATM, with a turnover of around £7m. The activity spans air, land and sea applications of gas turbines for power and propulsion. It is characterised by a very close integration of taught and short-course education and research, with 50-80 MSc students attending the Thermal Power course each year, and more than 80 full-time and part-time PhD students.

Director of the 'Rolls-Royce University Technology Centre (UTC) in Aero Systems Design, Integration & Performance' at Cranfield (Deputy Director 2008-2014);

The UTC is of major strategic importance to Cranfield due to its prestigious status and the business it attracts from Rolls-Royce and elsewhere (industry + academia). The UTC typically enrols more than 30 staff, more than 20 PhD candidates and more than 30 MSc candidates, with an annual research budget in excess of £4M.

Director of the 'Cranfield Air & Space Propulsion Institute' since Jan 2021;

The Institute supports a pan-university activity to promote and accelerate innovation across different disciplines and sectors in order to create new, revolutionary technologies for use in air and space propulsion. Key objective is to provide industry and academia with a pre-competitive environment for collaboration in low TRL research.


Cranfield interacts very widely with national and international research councils and organisations, (such as the ATI, the EPSRC, IUK, NASA, ESA, UKSA, DLR, NLR, ONERA and CIRA), industry and governments. It also values and develops long term relationships for the mutual benefit of its sponsors and itself. Within aerospace, these include Rolls-Royce, AIRBUS, SIEMENS, BOEING, Pratt & Whitney, SAFRAN Group, DSTL, BAE Systems, GKN, the MoD and many others.
