Biography

I am currently a Research Scientist at Data 61, CSIRO. Before that, I was a CSIRO Early Research Career (CERC) Postdoctoral Fellow in Data61, CSIRO and research associate at the University of Technology Sydney (UTS). In March 2021, I received my PhD degree from the Australia Artificial Intelligence Institute (AAII) within the Faculty of Engineering and Information Technology (FEIT), UTS, Australia. During my PhD study, I worked with Prof. Ying Zhang, A/Prof. Lu Qin, Prof. Fan Zhang, and Dr. Dong Wen in the areas of graph databases and efficient query algorithms. Prior to that, I received my M.S. degree (in Computer Science) and B.S. degree (in Software Engineering) both from Taiyuan University of Technology, China.
