I am currently a senior researcher at WeChat, within the Tencent Project UP (青云计划/技术大咖). I graduated from Peking University in 2025 under the supervision of Prof. Yadong Mu. Previously, I worked closely with Prof. Yuesheng Zhu at Peking University and Dr. Peilin Zhao at Tencent AI Lab. During my graduate studies, I was supported by the Presidential Scholarship, the highest honor for PhD students at Peking University.

My research primarily focuses on building trustworthy and responsible machine learning systems, encompassing training-time robustness, ownership protection, and machine learning industrial-level applications, such as recommender systems. I consistently served as a reviewer for machine learning venues, including ICML, NeurIPS, and ICLR. I am always open to external collaborations.
