I am a post-doctoral research assistant, working under prof Ian Shipsey in the OPMD (Oxford Physics Microstructure Detector) laboratory, principally on optical instrumentation for the Legacy Survey of Space and Time (LSST) camera, and involved in other detector projects also.
This work involves both experimental and simulation aspects - we have built a low noise, low vibration, cryogenically cooled optical test setup in the OPMD lab to measure subtle systematic effects (including the so-called "brighter-fatter" effect) on thick, back illuminated CCD sensors for the LSST camera, and also work on physically based (e.g. Sentaurus TCAD) simulations of these detectors to connect measured lab results to understanding of the device operation. This allows us to gain insights into device operating condition optimisations.
I was involved in the development of concepts for low cost per area timing and tracking detectors for the ATRAP experiment at CERN, and the SPEQTRE experiment for measuring positronium decays.
I am currently also involved in the specification, simulation, development and testing of the primary imaging cameras for the MAGIS-100 atom interferometer, and the AION-10 atom interferometer.
In addition to the physics of semiconductor detectors themselves, I have a keen interest in the development of readout electronics, particularly in the low noise analog domain, the development of DAQ software, and the development of semiconductor simulation software.
