About Me

I am a PhD student at École Polytechnique Fédérale de Lausanne (EPFL). I work in the Intelligent Maintenance and Operations Systems (IMOS) Lab under the supervision of Prof. Olga Fink. Previously, I received my master's degree at ShanghaiTech University and B.Eng. degree from Wuhan University (WHU). I also had the opportunity to visit Peking University (PKU) and City University of HongKong (CityU) as a research intern.

My current research focuses on Graph Machine Learning and Algorithmic Reasoning.
