I initially came to Brunel in 2004 as a research associate responsible for developing and testing imaging and spectroscopy detectors for use in space before being appointed as a lecturer in 2006. I currently work in the Sensors and Instrumentation Research Group carrying out radiation testing and characterisation of solid-state imaging and spectroscopy sensors and developing new dosimetry techniques for space and terrestrial applications. I have been involved with undergraduate and postgraduate teaching throughout my time at Brunel and I have developed and taught courses on different aspects of physics, sensors and instrumentation, computer programming and analogue electronics.
