Prof. Tong has more than 12 years’ research experience in ultra-precision machining and well-developed surface metrology skills. He has a diverse international research background that is inherently multidisciplinary and is situated at the interface between physics (molecular dynamics simulation and focused ion beam processing), machining/process control (cutting tool technology, tool-servo-based diamond machining, grinding, laser milling), and surface measurement (embedded surface metrology). In his previous job role in University of Huddersfield, he has been awarded two UK STFC-IPS project on transferring ultra-precision machining technologies to support the Manufacturing in the UK High-Gradient Cavities Disc for CERN (£268k, PI), and Optimised Metal Mirror Fabrication applied in Space (£450k, Co-I and led the freeform machining work package); the key Co-I and daily manager of an ultra- precision five-axis machine tool – Advanced Freeform Generator (£804k). He was a Co-I and steering board member on a €5M European Horizon 2020 research programme for mass production of functional structured surfaces (ProSurf, that included 4 international universities and 8 industrial partners, completed in June 2021).

Working with world-leading companies in this subject area, he is investigating ultra-precision manufacturing technologies and fast in-process quality control systems for next-generation HVM industries.
