Zijie Huang (黄子倢)

I am currently a Ph.D. candidate at University of California, Los Angeles (UCLA), where I am fortunate to be advised by Prof.Yizhou Sun and Prof.Wei Wang. My research interest lies in graph neural networks and machine learning in general, with a special focus on reasoning over dynamical systems (graphs) and knowledge graph modeling. My research is generously supported by Amazon Ph.D. Fellowship.

Before UCLA, I received my bachelor's degree of Information Engineering from Shanghai Jiao Tong University (SJTU) in 2019. I love piano, badminton and traveling.

I'm on the job market for year 2023-2024 !
