I received my Ph.D degree at the Chinese University of Hong Kong, under the supervision of Prof. Michael R. Lyu. I got my Bachelor’s (2018) and Master’s (2020) degree from Sun Yat-Sen University in InPlus Lab, under the supervision of Prof. Zibin ZHENG .

My research concerns AI for infrastructure, including AIOps, anomaly detection, log analysis, which aims to provide a more reliable cloud system.

Our project LogPAI provides an end-to-end solution to intelligently manage and analyze logs for modern production systems using machine learning techniques. So far, the project has received 3000+ stars and 800+ forks and the datasets Loghub have been downloaded for more than 80,000 times by 370+ organizations. Feel free to contact us if you have any questions.
