I am currently working at WeChat, within the Tencent Project UP (青云计划/技术大咖). I graduated from Peking University under the supervision of Prof. Yadong Mu. Previously, I worked closely with Prof. Yuesheng Zhu at Peking University and Prof. 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 interests focus on developing modern machine learning systems that incorporate security guarantees and industrial-level applications, such as recommender systems. I consistently served as a reviewer for machine learning venues, including ICML, NeurIPS, and ICLR. At Tencent WeChat, we are working towards building state-of-the-art recommender systems at scale. I am always open to external collaborations. If you are interested in working with me, please drop me an email through hanwenliu {at} msn.com
