🎓Ph.D. Student at Niulab @ Tsinghua University / 🌐AI/ML in RAN / 📸Spatial Intelligence
About
Hi, I am Zeyi Ren (任泽屹), a first-year Ph.D. student at Niulab in the Department of EE, Tsinghua University, under the supervision of Prof. Zhisheng Niu and Prof. Sheng Zhou. Before that, I obtained my M.Phil. degree from the Department of EEE, The University of Hong Kong, supervised by Prof. Yik-Chung Wu. I received my B.Eng. degree in Electronics and Information Engineering from Beijing Institute of Technology.
My research interests mainly focus on AI/ML in RAN🌐, spatial intelligence📸, and autonomous systems🏙️. During my undergraduate studies, I worked on localization problems in wireless networks, with a particular emphasis on cooperative localization.
I have worked as a visiting research intern at Shenzhen Research Institute of Big Data, collaborating with Prof. Yang Li, and as a research intern at Huawei Shanghai RAN Research Department, focused on AI/ML in RAN. I am also a Bilibili content creator 🎥 with 200k followers.
