About Me

I am a final-year master student at ShanghaiTech University advised by Prof. Ziping Zhao. Currently, I am also a research intern at Peking University (PKU). Previously, I received my B.Eng. degree from Wuhan University (WHU). During my undergraduate study, I spent a nice summer at City University of HongKong (CityU) as a visiting student.

My current research focuses on Graph Machine Learning.

I am excited to share that I will join the Intelligent Maintenance and Operations Systems (IMOS) Lab at École Polytechnique Fédérale de Lausanne (EPFL) as a PhD student in September!

Personal

In my free time, I enjoy traveling, reading, swimming, guitar and hiphop music. Besides, I like watching TV shows (my favorites are Vikings, Breaking Bad, Prison Break, etc.).
