Brief profile

I am a post-doctor in La Trobe University, Melbourne. Before that I was a one-year postdoctoral fellow in City University of Hong Kong in 2015-2016 and a half-year research assistant in University of New South Wales, Australia in 2015. I obtained my PhD in UNSW Australia under the supervision of Prof Ian Sloan, A/Prof Robert Womersley and Prof Michael Cowling and Master and Bachelor Degrees both from China Jiliang University.

I am interested in computational mathematics, stochastic analysis and machine learning, in particular, in the following areas.

  • Applied and Computational Harmonic Analysis
  • Monte Carlo and Quasi-Monte Carlo Methods on Manifolds
  • Computational Statistics and Stochastic Computation
  • Machine Learning
  • Computer Graphics

Research specialisation

- Numerical methods

- Statistical modelling
