Dr Gao’s research interest is focused on numerical modelling in tribology and biotribology with application of human joint implants.

  • Elastohydrodynamic lubrication simulation and analysis - on joint implants and industrial tribological components.
  • Joint implants wear simulation and analysis - Numerically prediction the wear of artificial hip/knee joints in daily activities, e.g. gait.
  • Musculoskeletal simulation and analysis - motion simulation; joints/ muscle force prediction.
  • Surface texturing design and optimisation - on the interfaces of tribological bearings to improve lubrication and reduce friction.

External activity

  • IMechE Charted Engineer (2019- now)
  • Editor of Special Issue ‘Modelling in Tribology and Biotribology’ in Lubricants 2022.
