How to Avoid Polarization in Recommender Systems with Dual Influence?
Invited talk at Chinese University of Hong Kong, Computer Science and Engineering Seminar
I am a postdoctoral researcher at Microsoft Research (New England), in the Economics and Computation group, hosted by Alex Slivkins.
I obtained my PhD in Computer Science from Harvard University in 2025 (advised by Yiling Chen) and BSc from Peking University in 2020 (advised by Xiaotie Deng). My research spans economics, machine learning, and theoretical computer science, focusing on mechanism design and information design for learning-based decision-makers, with applications to, e.g., advertising auctions and recommender systems. From 2023 to 2024, I interned at ByteDance and Google. I received the Siebel Scholar Award in 2025.
I will be an assistant professor in the School of Data Science at the Chinese University of Hong Kong, Shenzhen, starting in 2026.

My research direction is learning-based incentive design, an interdiscplinary topic in economics, machine learning, and theoretical computer science. I study mechanism design and information design problems with learning-based decision-makers. Example directions include:
My research is often motivated by the interplay between economic incentives and machine learning algorithms in real-world AI systems, such as advertising auctions and recommender systems.
