Personal profile


I am a Lecturer of Computer Science at The University of Western Australia (UWA). Before working at UWA, I was a research fellow at National University of Singapore from 2017 to 2019 and The University of Melbourne from 2015 to 2016 after completion of my PhD degree at The University of Melbourne in 2015. My research work has led to open-source machine learning systems such as ThunderGBM and ThunderSVM.

Research interests

Machine Learning

  • systems for machine learning, automatic machine learning, learning with resource constraints

High-Performance Computing

  • modern hardware (e.g., GPUs and multi-core CPUs) acceleration, distributed computing in heterogeneous systems

Data Mining

  • medical data analytics, financial data mining, data mining platforms

Current projects


  • supports classification, regression and ranking,
  • is often 10 times faster than XGBoost, LightGBM and CatBoost,
  • has attracted 430+ stars and 50+ forks on GitHub, and
  • is built on our related work: TPDS'19 and IPDPS'18.


  • supports all the functionalities of LibSVM including classification, regression and distribution estimation,
  • is often 10 to 100 times faster than LibSVM,
  • has attracted 1000+ stars and 140+ forks on GitHub, and
  • is built on these pieces of key related work: JMLR'18TKDE'18 and ICDM'14.
