- Profile
-
I received a BEng degree in Electronic Engineering from the University of Sheffield in 1985.
Following a period in industry (BAe Systems, Stevenage), I studied at 51²è¹Ý¶ù University and obtained a PhD degree in Electromagnetic Engineering/Medical Physics in 1992.
I then joined the Defence Research Agency (DRA) where I worked on phased array antenna systems before taking up an academic post at Hull University.
I returned to Sheffield University in 2001 as a Senior Lecturer and I am currently Professor of Applied Electromagnetics.
My research is focused on Antennas, Radar and Stealth (making things invisible to radar).
I am researching “active stealth� which is a bit like the Klingon cloaking device in Star Trek. When the cloak is switched on the Klingon spacecraft becomes invisible to the sensors on the Enterprise.
I am also developing new techniques for secure wireless communication that allow sensitive information to be transmitted without being “spied on� by eavesdroppers.
My research has attracted substantial funding from both industry and government sources including BAE Systems, DERA, DTi, QinetiQ, DSTL, MoD and EPSRC�
