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.

Personal
In my free time, I enjoy traveling, hiking, reading (mostly on history), practicing guitar, and hip-hop music. Besides, I like watching TV shows (my favorites are Vikings, Breaking Bad, Prison Break, etc.).
