Bio
I am a 3rd year Computer Science Ph.D. candidate in Big Data and Social Computing (BDSC) Lab at University of Illinois Chicago. My advisor is Prof. Philip S. Yu. Before joining UIC, I received my bachelor degree from Beijing University of Posts and Telecommunications and Queen Mary University of London in 2021. I am now an applied scientist intern at Amazon based in Seattle. I also interned in Walmart Global Tech and AWS Shanghai AI Lab DGL team. My research interests are Graph Mining, Anomaly Detection, and Fraud Detection. More information about me can be found in my Curriculum Vitae.
