Relevant Experience and Accomplishments

  • Research Associate, National Engineering Laboratory/ The University of Birmingham (1984-1987):- R&D work in water-based axial piston pump to be used in North Sea underwater oil rig engineering work
  • Automation Consultant, Inco Alloys Ltd., Hereford, UK (1987-1989):- Automation in nickel-based alloys production work
  • ACARL (2000-present):- With about HK$20M support from the HKSAR-ITC and industry the Advanced Coatings Applied Research Laboratory (ACARL) was planned and established at CityU. The range of research work includes superhard nanocomposite coating, friction reduction tribological films and surface engineering. The ACARL team also focuses on tackling industrial-based problems. As a result, the team continues to secure Innovation and Technology Fund industrial based projects from the ITC, HKSAR. Contracted research works from International renowned companies such as GM, SKF, Johnson Electric, etc. were also conducted.
  • IEA-AMT-IA (since 2012):- Lawrence was invited to join the "Implementing Agreement on Advanced Materials for Transportation (AMT IA)" which is part of the International Energy Agency (IEA). The focus is to facilitate the introduction of new materials technologies that have the potential to significantly reduce oil consumption, enhance energy security, protect the environment, and promotes economic development of participating countries (extracted from AMT-IA Strategic Plan 2013-2018).
