- Profile
-
I am a Professor in RF Engineering, in the Communications Research Group.
Prior to starting at The University of Sheffield in 2015, my career has been as a practising RF Engineer in industry:-
- Tunstall Healthcare Ltd (Principal RF Engineer & Radio System Architect) 2011-2015
- Cambridge Consultants Ltd (Principal RF Engineer, in Wireless Business Unit) 1996 - 2011
My industrial expertise is in building innovative, bespoke, wireless systems that require a balanced and holistic view of RF / Digital / DSP / Protocol aspects to achieve best partitioning for performance vs cost trade-off. I am experienced in adapting COTS radio protocols and creating bespoke protocols.
I am particularly experienced and passionate about hardware design, for both high volume and low volume manufacture.
My reach extends from the pre-specification creation process, through all theoretical aspects of RF design, to the practical lab bench development and field test; all core to the creation of a mass producible item. I’m also experienced at talent identification and selection for developing high capability teams.
