My name in simplified Chinese: 陈炤桦 (Chén Zhàohuà).

I am a fifth-year Ph.D. student at Center on Frontiers of Computing Studies (CFCS), School of Computer Science, Peking University, honored to be advised by Prof. Xiaotie Deng. I received my BSc (Summa Cum Laude) in artificial intelligence (Turing class) from Peking University, 2021. I visited The University of Hong Kong from May to October, 2025, hosted by Prof. Zhiyi Huang. In the summer of 2026, I will join Taobao & Tmall Group as a senior algorithm engineer.

I am working on various topics in the interplay of computer science and economics, also known as algorithmic game theory.

I am, in particularly, interested in the (complicated) game-theoretic interaction between the servicing platform and served targets (e.g., advertising platform v.s. advertisers, e-commerce platform v.s. sellers, platform v.s. users, etc.), mainly in the following aspects:

• How can the platform design algorithms to reach its goal or help targets reach their goals?
• How can the targets conversely exploit the platform's algorithm to better benefit themselves?
• How can one simultaneously benefit the platform and their targets?
