Dr. Rollinson's research expertise is in small-scale sustainable energy engineering, particularly energy from waste processes such as pyrolysis and gasification. He specialises in reactor design and optimisation, process engineering, fuel and product characterisation, and reaction kinetics.

Following a PhD at the University of Leeds on steam reforming of urea, and then post-doctoral research in Qatar on solar reactors for methane cracking, Dr. Rollinson spent three years at the University of Nottingham as Research Fellow on the gasification strand of UK/India EPSRC project Rural Hybrid Energy Enterprise Systems, followed by a year as a Lecturer in Mechanical Engineering at the University of the Highlands and Islands. For the last few years Dr. Rollinson has also worked independently and as technical advisor for UKWIN, on municipal solid waste gasification. In addition, he was awarded a grant to complete research on the world's last industrial stone grinding water wheel in his home town of Castleford, West Yorkshire.
