Computer Science and Engineering

I'm an Associate Lecturer at UNSW's School of Computer Science and Engineering. I completed my PhD in computer science at the Data and Knowledge Research Group, UNSW, under the guidance of Prof. Xuemin Lin and Prof. Wenjie Zhang. I hold an MEng degree in Mathematical Computation (First Class Honours) from UCL, where I earned the IBM sponsorship for Best Undergraduate Final Year Project. My research interests encompass database systems, graph data processing, and big data analysis. For more information, please visit my personal website.

I'm actively looking for self-motivated MPhil and PhD students.
