David is a Royal Society University Research Fellow and Professorial Fellow (Research) within the Silicon Photonics group of the Optoelectronics Research Centre. David leads research in the area of photonics for computing systems. His career in Photonics began with a year in industry at Nortel Networks in Paignton. David joined the University of Surrey in 2001 as an undergraduate student studying electronic engineering. He subsequently undertook PhD studies under the guidance of Professor Graham Reed investigating optical switching devices in silicon. From 2008 he worked as a research fellow in the same research group on a number of projects and different optical devices in silicon although focusing mainly on high speed active devices and their integration with other photonic and electronic devices. David moved to the University of Southampton in 2012 David taking up the role of senior research fellow. David has published over 40 journal papers, 10 patent applications and around 100 conference papers in the area of silicon photonics. David has served on 4 conference committees including IEEE Group IV Photonics and SPIE Photonics West.
