Background

For a large part of my working life, I was in full time employment at the Central Research Laboratories (CRL) of EMI, which became Thorn EMI and then Scipher. CRL was founded in the 1920s, and has a long record of achievement and technical innovation including the world's first public high definition television service, the first modern stereo records, radar to counter the WW2 night bomber, and the X-ray scanner for which the late Sir Godfrey Hounsfield, who was also based at CRL, received a Nobel Prize for Physiology or Medicine in 1979.

I worked as a Staff Scientist in the Wireless Group at CRL, and had experience in various other departments of the Laboratories, have a Masters' Degree in Microwaves and Modern Optics, and a BSc in Microelectronics and Computer Engineering. I am registered as a Chartered Engineer with the Engineering Council, and am a Member of the IET (formerly the IEE) and the IEEE.
