PhD in Optics, Xi’an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences. 2011
BSc in Applied Physics, National University of Defense Technology, China. 2006


Dr Gong graduated in 2006 with BSc from National University of Defence Technology. He then studied for PhD in State Key Laboratory of Transient Optics and Photonics, Chinese Academy of Sciences. During his PhD study, he was awarded the honor of ‘Daheng’ Scholarship in 2009, ‘Western Student’ Scholarship in 2010, and Chinese Academy of Science Dean Reward in 2011, respectively. He completed his PhD in May 2011 and then joined Wireless and Optoelectronics Research and Innovation Centre (WORIC) at the University of South Wales.

At WORIC he successfully delivered many new concepts. He worked on Carbon Trust funded project on highly efficient grating enhanced organic light emitting diode from 2011 to 2013 and then worked on a Welsh A4B grant on novel optical wavelength conversion in 2014. In 2015 he was appointed as a lecturer and module leader of BSc Optoelectronics for Communications.

His current research interest mainly includes novel integrated photonic devices/systems. He has authored 3 patents and has published >40 journal papers with WOS H-index of 20 and number of citations exceed 1100. He is a peer reviewer for a number of leading optical journals. He has supervised several PhD and graduate students.


My research interest includes novel photonic materials, nanophotonics technologies (plasmonic metamaterials, photonic crystals, 2D materials etc), LED/OLED lighting, laser technologies and novel integrated photonic devices/systems for high capacity/speed telecommunication, chemical/medical biosensing, and high efficiency lighting etc. I am experienced in full-wave 2D/3D optical design/simulations (FDTD, FEM, RCWA, Matlab programming) and laser/E-beam nanofabrications and characterization.

1. Principle investigator (2017), a PhD programme (funded by Mingliu Ltd) to develop novel electric infrared heater based on plasmonic photonic crystals.
2. Co-investigator/Project Manager, 2013-2014, £100k A4B project on “Proof of Concept for a Novel All-Optical Wavelength Conversion” ,
3. Research Fellow, 2011-2013, £2.5m Carbon Trust project “High efficient grating-based organic light emitting diode”
