Who I am

I am currently an Associate Lecturer in the School of Computer Science and Engineering at the University of New South Wales (UNSW) and a Visiting Database System Scientist at Enmotech Data AU. I obtained my PhD in Computer Science from UNSW under the supervision of Prof. Xuemin Lin (Member of the Academia Europaea, IEEE Fellow) and Prof. Wenjie Zhang (ARC Future Fellow) at the Data and Knowledge Research Group. Prior to that, I pursued my MEng in Mathematical Computation (First Class Honours) at the Computer Science Department at University College London (UCL), where I was awarded the IBM sponsorship for the Best Undergraduate Final Year Project (First Place). In 2018 and 2021, I worked as an intern at Alibaba DAMO Academy and Google, respectively.


Stuff I do

My expertise lies in developing efficient and scalable algorithms and systems for managing and processing large-scale data, including graph data, relational data, spatial-temporal data, and high-dimensional data, etc. I'm also interested in various other computer science areas, such as information retrieval, distributed systems, and machine learning.

  • Programming

    Python Rust Java C
  • Data Analysis

    Python Spark Neo4j PostgreSQL
  • Machine Learning

    Python R Matlab TensorFlow
  • Web development
