Yilin Li

I am a Ph.D. student in the Department of Computer Science and Engineering at The Chinese University of Hong Kong, advised by Prof. Hanrui Zhang.

Before joining CUHK, I worked as a data scientist at Mercari Japan, where I worked on mathematical optimization, predictive modeling, and experimental design for personalized marketing strategies. I received my bachelor's and master's degrees in Software Engineering from Beihang University.
