My name is Jiaxin Mao (毛佳昕, in Chinese). I am a postdoctoral research fellow at the Department of Computer Science and Technology at Tsinghua University, working with Prof. Shaoping Ma and Prof. Yiqun Liu. My research lies in the area of Information Retrieval, Web Mining, and Applied Machine Learning. With a wider interest in how people interact with the huge amount of information on the Web, I currently focus on User Behavior Analysis for Web Search Engines.

I am the ACM SIGIR Student Affairs Co-Chair since 2018 and served as an ACM SIGIR Student Liaison during 2017-2018, please contact me if you have any question about SIGIR-student matters.

I also served as reviewer and PC member for TOIS, TKDE, JASIST, SIGIR, WWW, CIKM, CCIR, and CCL.
