Hi! I am a PhD candidate at School of Computer Science and Engineering, Nanyang Technological University, supervised by Prof. Yiping Ke.
Prior to NTU, I received a B.S. in Software Engineering from Beihang University in 2020. I worked with Prof. Jie Tang at Tsinghua University on Natural Language Processing. In 2019 and 2020, I was a research intern in Knowledge Computing Group, Microsoft Research Asia.

My research interests lie in representation learning and healthcare, especially on graph neural networks. I do believe these fields make invaluable contributions to the real world.

Miscellaneous

Aside from my curiosity about computer science and my study preoccupation, I am also a big fan of music and go game. I would like to listen to the concert, play guitar or watch go game competition in my free time. If this involves sports, I favor swimming since it enhances my self-control and it is a benefit in my health insurance and spirit.
