Overview
I am a Lecturer at Cardiff School of Engineering. I am a particle physicist with research interests in lightning, lightning phenomena, and lightning interactions with physics and engineering applications. I am based in the Lightning Laboratory, part of the Advanced High Voltage Research Centre, within the Electrical Engineering Department. My expertise is in the characterisation of high voltage and high current laboratory-generated lightning arcs and their interactions and related phenomena, using a variety of advanced optical, high-speed, schlieren and spectrographic techniques. My research is cross-disciplinary involving physics, electrical engineering, mechanical engineering, chemistry and material science, and I work closely with other laboratories within the school of engineering, such as the Structural Performance Laboratory and the Wolfson Centre for Magnetics.
I am Head of Year 3 and a member of the Senior Teaching Committee, and Industrial Lead and member of the Industrial Board for the Mechanical Engineering Department. I teach Engineering Control and laboratories, as well as Matlab and Solidworks. I supervise a number of undergraduate and postgradute sudent projects each year in a variety of engineering fields, which also includes heritage engineering project via the National Museum of Wales.
