Greetings! I'm Zhi-ning LIU (刘芷宁).

GitHub Zhihu Steam PhD

你好! / Hello! / 안녕하세요! / こんにちは! / Здравствуй! / Bonjour! / Guten Tag! / Hola! / Ciao! / السلام عليكم!

I’m a Ph.D. student in Department of Computer Science, University of Illinois at Urbana-Champaign, working with the very nice Prof. Hanghang Tong. Before joining UIUC, I received my B.S. and M.Eng. in Computer Science from Jilin University in 2019 and 2022, respectively. During my time at Jilin U, I was fortunate to have Prof. Yi Chang as my advisor, and had the pleasure of working with Dr. Jiang Bian, Dr. Wei Cao, Dr. Pengfei Wei, and Prof. Jing Jiang.

My goal is to build practical machine learning systems that promote fairness and equity. I am particularly interested in developing algorithms and open-source softwares for unbiased, efficient, and robust learning from skewed data in real-world applications. My recent interest lies in topics related to graph data mining, especially, learning from real-world graphs with skewed data distribution.
