My research interests center around the design, development and operation of CCD and CMOS camera systems, with a focus on their application in the space environment and the image degradation that arises due to radiation damage. I am particularly interested in testing and developing cryogenic irradiation techniques, as well as investigating potential new technologies such as P-Channel CCDs. Currently, I am leading cryogenic irradiation campaigns on detectors for the Euclid mission, testing novel P-channel CCDs, and analyzing in-orbit radiation degradation data from the Gaia mission.
I am passionate about teaching and currently serve as Chair of S818 Space Science. I am also an Associate Lecturer for the SM123 Physics and Space module. I have served on several module teams, including S217: Physics from Classical to Quantum and SXPS288: Remote Experiments in Physics and Space.
I am a passionate STEM ambassador, and enjoy interacting with local school, exhibitions, and the media. Some highlights include:
