I received my B.Sc. degree in Electrical and Electronic Engineering from the University of Birmingham and my M.Sc. and Ph.D. degrees in Electrical and Electronic Engineering from the University of Manchester, UK, respectively. Currently, I am Chair Professor of Wireless Communications at the University of Sheffield.

My research is focused on wireless communications systems specialising in physical layer signal processing, radio resource management and wireless network planning. I have pioneered research on energy efficient mobile cellular communications, the mathematical modelling of CSMA based MAC protocols for WiFi, iterative block coding for wireless communication systems and spreading sequence design for CDMA wireless communications.

I was an entrepreneur, being the cofounder and CTO of Supergold Communication Limited (1997-2007), a start-up that participated in the standardisation of IEEE 802.11g with the M-ary Bi-Code Keying proposal. In the framework of Mobile VCE, I was the Academic Coordinator of the Core 5 Green Radio project (2009-2012) and a leader in establishing energy efficiency as a global research field in wireless communications systems.

I have led 22 major research projects as the principal investigator and participated in 2 as a coinvestigator with a total research spend of approximately £12M. My current EPSRC project portfolio includes the DDmmMaMi, FARAD and SERAN projects as well as CommNet2. I have published 315 journal & conference papers, book chapters, patents and technical reports; graduated 24 Ph.D. and M.Phil. students; and participated in standards, consultancy and expert witness activities within the wireless sector.

Currently, I am leading the UK Research Strategy Community Organisation in Communications, Mobile Computing and Networking within the EPSRC portfolio (www.commnet.ac.uk). I am also a Director of the mVCE (www.mobilevce.com), a Chartered Engineer IET member and Senior IEEE member.
