Research Activities

  • Avalanche photodiodes with electron-only ionisation for “noiseless” avalanche process (F<2) and extremely high gain-bandwidth product (>500 GHz).
  • Design, modelling and characterisation of single photon avalanche diode (Si, GaAs, InAlAs, AlGaAsSb)
  • High speed avalanche photodiodes for optical fiber communication, utilizing very thin avalanche region for improved excess noise and bandwidth (InP, InAlAs, AlGaAsSb lattice matched to InP)
  • Novel multi-colour detectors for radiation thermometry
  • High sensitivity detectors for infrared wavelengths bands NIR, SWIR, MWIR, LWIR and VLWIR
  • Improving energy resolution of soft X-ray detection using avalanche photodiodes


  • Deputy Director of Research and Innovation for Faculty of Engineering
  • Member of Departmental Athena Swann
  • Chair in Photon Detectors, Leads the Advanced Detector Centre
  • Teaching EEE337, EEE348 and EEE6216
  • Undergraduate tutoring and project supervision


I started as an undergraduate at the Department of Electronic and Electrical Engineering (EEE), The University Of Sheffield in Sept. 1996. Following a rewarding 1st class degree, I was fortunate to be given a full scholarship to pursue a PhD degree at EEE. The PhD degree significantly broadened my knowledge in Engineering as well as inspired my desire to continue learning. EEE has provided a wonderful environment for me to explore fundamental engineering questions, advance research to generate lasting impacts and to share my experience with students and researchers. My career progression to date has been supported by some great colleagues and students. They have helped to enrich my experience in work as well as outside work. I enjoyed sharing and exploring good food with them, with regular trips to different restaurants around the University and while attending conferences abroad.
