He joined UoB as a Senior Lecturer in 2002, becoming professor in 2006. He received his PhD in industrial automation from East China University of Science and Technology (href="http://www.ecust.edu.cn/">www.ecust.edu.cn), Shanghai, China, in 1995. From 1997 to 2001, he was a postdoctoral research fellow with University college London, Imperial College London, and Oxford University. Guillaume de la Roche has been working as a research fellow at the Centre for Wireless Network Design (UK) since 2007. He received the Dipl-Ing in Telecommunication from the School of Chemistry Physics and Electronics (CPE Lyon), France, an MSc degree in Signal Processing (2003) and PhD in Wireless Communication (2007) from the National Institute of Applied Science (INSA Lyon), France. Alvaro Valcarce obtained is MEng in telecommunications engineering from the University of Vigo (Spain) in 2006. During 2005 he worked at 'Telefonica I+D' in Madrid (Spain), integrating an applications-streaming platform into an 'ATG Dynamo Server', as well as developing a system for applications-on-demand'. David Lopez-Perez received his bachelor and master degrees in telecommunication from Miguel Hernandez University, Elche, Alicante (Spain) in 2003 and 2006, respectively. He joined Vodafone Spain in 2005, working at the Radio Frequency department in the area of network planning and optimization. he participated in the development of the Vodafone Automatic Frequency Planning tool for GSM and DCS networks. Enjie Liu is a Senior Lecturer at the Department of Computer Science and Technology of the University of Bedfordshire. She joined UoB in 2003. She is a member of the Networking teaching group in the department and responsible for delivering both wired and wireless modules to undergraduates as well as post graduates. She received her PhD from Queen Mary College, University of London in 2002. Then she worked as research fellow with the Centre for Communication Systems Research (CCSR), the University of Surrey. She was grated a Newly Appointed Lecturers Award by The Nuffield Foundation. Hui Song is a PhD student and research associate at the Center for Wireless Network Design (CWiND), University of Bedfordshire. His interests is network planning and optimization technologies. His current focus is on modeling OFDM fading channels. before joining CWiND, he was the manager of eh technology department at Bynear Telecom Software Ltd, Shanghai, China. There he was responsible for developing and maintaining the nation-first network planning and optimization suite (including GSM, WCDMA and TD-SCDMA). Song holds a mathematics degree from Fudan University, Shanghai, China. He currently resides in the United Kingdom.
