Overview

James received BSc and MSc degrees in physics from Xiamen University, P.R. China, and a PhD in Electrical and Computer Engineering from National University of Singapore (NUS), Singapore.

He is currently a Reader at Bangor University and a visiting professor at Northeastern University (NEU, Boston, USA). He was awarded a Leverhulme Trust Research Fellowship to take one year research leave (2022-2023) to conduct new research in NEU on deep learning assisted  microsphere nanoscopy and on-demand photonic design.

His research expertise lies in the fields of laser-based manufacturing, nanophotonics, metamaterials, solar energy, fiber sensors,  with special focuses on super-resolution microscopy, imaging, sensing, laser micro and nano processing for industry. He has strong publication and citation  records with an H-index 42 (2022). He is an elected senior member of Optica (2017) and widely known as the leading pioneer of microsphere and nanosphere-based superlens technologies.

Research

1) Dielectric superlens and super-resolution microscopy

 James and his ‘Bangor Superlens Team’ is well-known for their pioneering works on microsphere and nanoparticle-based dielectric superlens technologies, including ‘microsphere superlens’ and ‘microsphere nanoscope’ (2011, published in Nature Communications), ’spider silk superlens’ (2016, Nano Letters) and ’nanoparticle superlens’ (2016, Science Advances). All these works were widely publicised and appeared in major media including BBC, New York Times, Daily Mail, Independent, Australian BC, China Xinhua and a huge number of science and engineering websites, as well as in RCUK’s ’50 big ideas for the future’. James is the 2016 finalist for ‘Research Excellence Award’ and ‘Dissertation/thesis supervisor of the year’ of Bangor University. He was also selected as a member of 2015 Welsh Crucible cohort (group of young Wales-based leaders in academia, industry and business). He received Most Outstanding R&D Staff Merit Award in 2005 for his contribution in laser cleaning at DSI Singapore.

The latest nanoparticle superlens developed by James and his team is one of the most powerful superlens in the field at present. Compared to other superlenses, Bangor’s superlens produces shaper and better-quality images of super-resolved nanoscale features, including for example 50-nm standard polystyrene nanoparticles, 45-nm gaps in semiconductor chips and 90-100 nm adenoviruses. The team is currently developing a superlens-integrated biochip device and a superlens-based nano-imaging & fabrication system.

2) Laser-based advanced manufacturing, material processing for industry

The team perform research into laser cutting, welding, drilling, texturing, marking, cleaning, polishing,  and others (e.g. laser improvement of seed germination and yield) for various industrial applications. The school host a wide range of laser facilities at Bangor, including nanosecond fibre and UV lasers, high-power high repetition rate femtosecond laser and CO2 lasers.  Various characterisation tools including advanced 3D laser scanning microscopes (Olympus OLS5000 and DSX1000) are also available for the precise measurement and characterisation of laser-processed samples. The research is currently supported by major pan-wales project “Centre for Photonics Expertise (CPE)” which supports welsh industry (all sectors including electronics, optics, aerospace, automotive, energy, nuclear, etc.) in developing new products, process and services. We have been working with companies including Qioptiq, TataSteel, Welsh Slates, Trascend Packaging, among others.   The team has developed very unique capability in direct laser nano marking using specially developed superlens with sub-100 nm resolution.

3) Fiber-based optical sensors and devices

  • Novel surface-functionalized FBG/LPG sensors.
  • Optical fiber decorated with microsphere lenses
  • Optical fiber trapping, imaging, sensing 

4) Shift-free metamaterial filters:

The team are among the few groups who have successfully developed new metamaterial-based, shift-free, wide-angle, narrowband filters for anti laser striking application and working towards new application in underwater optical communications.

5) Solar cell (SPARCII project)

  • Novel laser trapping nanostrucuters and metasurface for high efficiency solar cell;
  • solar-driven nanoparticle synthesis and water splitting
  • Nanophotonics and plasmonics in perovskite solar cells
  • Advanced laser manufacturing technology for solar cell

6) Data-driven intelligent Manufacturing and nano-imaging

  • AI and ML driven advanced manufacturing
  • Advanced imaging with AI and ML
  • Intelligent robotic manufacturing
