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. During my PhD, I have also worked with Prof. Jhony H. Giraldo at Télécom Paris, Institut Polytechnique de Paris, as a visiting PhD student.

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 Generative Model and Graph Machine Learning. Feel free to contact me if you have anything would like to discuss!
