Profile

I received my BSc degree in Electrical and Electronic Engineering from the University of Birmingham and my MSc and PhD degrees in Electrical and Electronic Engineering from the University of Manchester.

I am the Chair Professor in Wireless Communication at the University of Sheffield and I am a Fellow of the Royal Academy of Engineering (FREng).

In the field of wireless communications, I have made significant contributions to waveform and energy-efficiency design for radio access networks (RANs) and I have translated significant research into industry through standards, products, and practices.

My research is focused on wireless communications systems, specialising in radio systems engineering, physical layer signal processing, and energy-efficient (EE) wireless networking.

As Co-Founder and CTO of Supergold Communication Limited, I accomplished strategic breakthroughs in determining the IEEE802.11g Wi-Fi standard. Also, I have developed standardised practices for measuring EE in RANs and produced software-tools for modelling RAN performance.

I have led 27 major research projects with a total research spend of approximately £29M. I led the UK Research Strategy Community Organisation in Communications, Mobile Computing and Networking within the Engineering and Physical Sciences Research Council portfolio (CommNet II, EP/N007824/1) and currently, I am the director of the UKRI National 6G Radio Systems Facility (EP/X030016/1).
