Dr Stuart Hillmansen is a Senior Lecturer in Electrical Energy Systems within the Department of Electronic, Electrical and Computer Engineering at the University of Birmingham. His main area of research interest is in hybrid traction systems for use in railway vehicles. He is a member of the Birmingham Centre for Railway Research and Education in the University of Birmingham. His recent research has been supported by the European Commission, EPSRC, Network Rail, Arup, Advantage West Midlands, the Department for Transport, The Technology and Strategy Board, Atkins Rail. He has authored a number of papers on railway energy consumption and presented the work at a number of international conferences.

Dr Hillmansen leads the Railway Traction Systems Group in the University of Birmingham. The main achievement since Dr Hillmansen joined Birmingham is to have re-established the University’s international reputation for traction research, and to have produced fundamental research which has a direct and current benefit to the railway industry. The group have developed leading expertise in hybrid rail propulsion and our expertise and research results have been used by the UK Government to inform the procurement of new rolling stock. This work is continuing and is now supported by the Energy Systems Integration Laboratory which has been funded by AWM and ERDF. This laboratory will assist the team in producing outstanding research outputs for many years to come.

Research
As head of the Railway Research Group's traction systems research, Dr Hillmansen has developed key themes, built up its reputation internationally in both academic circles and industry and co-ordinated its dissemination.

Developing key themes
Improving the energy efficiency of railway systems relies on frontline developments in railway traction systems. Developing and testing cutting edge hypothesis in this field not only creates interesting and challenging PhD programmes for the team, but ensures that the practical applications of the research are timely and of great importance to both industry and the Department for Transport (DfT) both of whom have carbon reduction strategies. This has led to a number of deployments with direct or collaborative funding. Software developed by Dr Hillmansen’s team for train simulation and optimization is not only being currently applied on the UK's railways but also internationally through collaborations outside the EU in the USA and far east. An example is the application of the simulator to the assessment of new rolling stock designs on the Singapore Mass Rapid Transit system. Previously the software was applied to other high-speed routes in the UK to support the development of the Government's technical specification for the next generation of high speed rolling stock (2007-8). Advanced instrumentation systems designed by Dr Hillmansen’s team are deployed in passenger services in the UK. These include instrumented vehicles and infrastructure on the Merseyrail network (with direct funding from the DfT and co-funding by EPSRC).

Industry
The dissemination activities of the group regularly attract the attention of the industry and we often showcase our work in high-level meetings with senior members of high profile companies. The group work closely with Atkins rail group and are participating in a KTP with them. Our multi-train simulator will be fully incorporated in Atkins' suite of rail related design and analysis tools. Dr Hillmansen is principle investigator of the Energy Storage and Integration Laboratory (established in April 2010 and funded by AWM and ERDF through the Science City programme) that supports the research through cutting edge experimentation and validation of simulation studies. The laboratory has already generated significant interest from the industry, and has been featured in railway and engineering publications. The laboratory will support our long term research aspirations and will help translate the outputs from our research into tangible industry impacts.

UK profile
Recognition of the value of Dr Hillmansen’s research can be seen from the invites from key UK bodies. The Government's Energy and Climate Change Select Committee requested Dr Hillmansen’s evidence (both oral and written (2008)) to inform their report on Low Carbon Technologies in a Green Economy. The DfT's Technical Strategy Advisory Group requested Dr Hillmansen’s contribution in developing a future strategy for energy for the railway industry (2008). Dr Hillmansen also has been invited to contribute to the development of the future technical strategy of the railway, and have supported the Government's Technical Strategy Advisory Group on a number of occasions. Since 2005, Dr Hillmansen has been a member of the DfT chaired Future Fuels Technology Group.

The group regularly present their results to The Railway Industry Association, the Railway Safety and Standards board and the Vehicle Train Energy System Interface.

The IMechE appointed Dr Hillmansen as an editorial board member (Proceedings of the Institution of Mechanical Engineering Part F: Journal of Rail and Rapid Transit) and as a member of the Conferences and Seminars Committee

International profile
On the international stage Dr Hillmansen is heavily involved with EU FP7 research projects, and is principle investigator on two projects. Both projects are likely to lead onto significant future funding. Dr Hillmansen co-chaired the 4th International Railway Traction Systems Conference attended by delegates from the UK, the USA, Australia, Far East and the EU. Dr Hillmansen is regularly invited to address international conferences (including high profile conferences in Japan and Hong Kong) and to peer review papers from international journals. The group are collaborating with Vehicle Projects INC in the USA, who have developed a number of fuel cell demonstrators (including a switcher locomotive), and have jointly prepared an article for publication. In Singapore, our simulator is being used to assess the performance of the latest rolling stock running on their metro.

Publications
Results from Dr Hillmansen’s research has been published in literature and are published in numerous conferences. The research is now established and the rate of publications is about 4-5 journal papers per year and which is in addition to several conferences (attended by the research team and students).
