Liu Yang is an assistant professor in the Key Laboratory of Intelligent Information Processing of Chinese Academy of Sciences(CAS), ICT, CAS.

He got his PhD from Institute of Computing Technology Chinese Academy of Sciences under the supervision of Prof. Qing He, and co-supervised by Prof. Xiang Ao.

From Feb 2022 to Feb 2023, he was a visiting scholar in the NExT Research Centre, National University of Singapore(NUS), adviced by Prof. Chua Tat-Seng. Also, he worked with Prof. Fuli Feng and Prof. Yunshan Ma.

Previously, he received the B.S. degree in Mathematics from Nanjing University (NJU) in 2017.

My research interest includes graph machine learnig and AI safety. I have published 20+ papers at the top international AI conferences such as WWW, ICLR, KDD.

Our group welcomes visiting research intern students and feel free to reach out to me.
