Biography

"Presently I am Senior Research Fellow at the Centre for Electronic Imaging (CEI). Most of my work is focused on the design and evaluation of novel image sensors for scientific applications, manufactured in CMOS technology. The research topics I am working on now are electron multiplication in CMOS imagers, achieving full depletion in CMOS sensors for maximum quantum efficiency, dynamic charge collection effects in CCDs, and radiation damage effects. From 2001-2008 I worked at STFC Rutherford Appleton Laboratory (RAL) on the development of 3 generations of column-parallel CCDs and 2 generations of CMOS-based in-situ storage image sensors, readout ASICs and support electronics for the vertex detector at the proposed International Linear Collider. I also lead the development of one of the first devices in the world incorporating buried channel CCD in specially modified 0.18 μm CMOS process. From 2008-2012 I was with the technology consultancy company Sentec Ltd. in Cambridge (UK), working on a variety of new technologies for industrial and consumer applications. "

Research Interest

My research interests are in semiconductor image sensors for science, where the term "imaging" covers everything from infrared, visible and X-ray wavelengths to minimum ionising particles in high energy physics.
