Hi, I am Zixu Li (李子旭).

I am a first-year Ph.D. student in the doctoral phase of an integrated Master–Ph.D. program in Artificial Intelligence at Shandong University, under the supervision of Prof. Liqiang Nie and Prof. Yupeng Hu. In 2023, I received my Bachelor’s degree in Data Science and Big Data Technology from Shandong University.

My research interests include multimedia computing, information retrieval, and approximate nearest neighbor search.

I warmly welcome academic discussions and potential collaborations. Please feel free to contact me if you are interested in my research or possible cooperation.

欢迎就我的研究方向展开学术交流与合作,如果您有相关研究兴趣或合作意向,欢迎随时联系我。
