Callum received a first class bachelors degree with distinction, in Electronic Engineering at the University of Surrey in June 2011. Upon completion of his degree he was awarded the Oclaro Technology prize for best performance in the Optoelectronics module, taught by Graham Reed, and the IET prize for best final year project for his work on anti-reflection coatings for solar cells.
He completed his placement year with BAE Systems where he was working on high speed electronics and radiation detection. His PhD, at the University of Southampton, was in the area of waveguide integrated germanium photodetectors at a wavelength of 1.55 µm.
He aims to develop high quality germanium-on-silicon growth techniques, along with optimal device designs and precise ion implantation that will enable detectors to be fabricated with improved performance on the current state of the art. He is also the self-proclaimed social secretary of the group, responsible for organising events and team building days out.
