Jamie is a Microelectronics Design Engineer working in the CMOS Sensors Group. He joined as Graduate Engineer after studying electronic engineering at the University of York.

We develop image sensors for scientific applications, designing sensors for a wide range of customers using industry-standard CAD tools.

The nature of the work in the group is mostly grant-funded, from academic and/or research institutions, which makes each new project varied and interesting. I worked initially as part of a team at CERN designing digital control logic for an ASIC for the Large Hadron Collider. I then worked with Imperial College designing a readout chip for the CMS calorimeter.

Since then I have worked on several pixel sensor designs, most recently a CMOS based system investigating "enhanced functionality" pixel sensors. This concept is a step forward from traditional sensor designs that have minimal circuitry in every pixel and has the potential benefits for high frame-rate imaging and applications involving high light intensity (laser) or ionising particles (particle physics). The prototype design is undergoing evaluations at UCL and Liverpool Universities, and the Institute of Cancer Research (ICR) in Surrey where the suitability of this device for a number of applications including medical X-Ray Imaging is being tested.

The success of this project has led to a patent application, two invitations to talk at international conferences and helped secure funding for further work. I am now working on a prototype development programme for the International Linear Collider project that, if successful, will implement CMOS image sensors in layers over an area of 2000 square meters to track particles after a collision.
