Dr James Kelly
Biography
I am a Lecturer (Assistant Professor) in Microwave Antennas within the Department of Electrical and Electronic Engineering and a member of the Institute for Communication Systems (ICS) at the University of Surrey. I joined the University of Surrey in October 2013. Before this I was a Lecturer at Anglia Ruskin University in Cambridge, England. From 2007 to 2012 I worked as a research fellow/associate at Loughborough University, as well as the Universities of Birmingham, Durham, and Sheffield.
I have approximately 2.5 years of industry experience. From 1999 to 2000, I worked for the International Rail Vehicle Consultancy, Interfleet Technology. During 2001 and 2012, respectively I worked within the Rolls-Royce Strategic Research Centre and at Airbus Defence and Space Ltd (then EADS Astrium).
I received the Master's degree in electronic and electrical engineering (2002) and the Ph.D. degree in microwave filters (2007) from Loughborough University, Leicestershire, England.
I have published over 80 academic papers in peer reviewed international journals and conference proceedings. In 2009 I delivered the key note speech at an IET seminar in London. The topic of the seminar was “Adaptable and tunable antenna technology for handsets and mobile computing products”. I also co-chaired a session on adaptive antennas for software defined radio during the 2009 IEEE International Symposium on Antennas and Propagation, in Toronto, Canada.
I am a member of the Institution of Engineering and Technology (IET), the Institute of Electrical and Electronics Engineers (IEEE), and the IEEE Industrial Electronics Society. I frequently act as a referee for various international journal publications, including the IEEE Transactions on Antennas and Propagation, the IEEE Antennas and Wireless Propagation Letters, and the IET Microwaves, Antennas & Propagation.
