I am Kaidi Zha (查恺迪), a fourth-year undergraduate at Tsinghua University, where I study Mathematics and Physics. My research focuses on multimodal models and agents. I expect to begin my Ph.D. at the School of Artificial Intelligence, Shanghai Jiaotong University, in 2027, supervised by Prof. Qibing Ren.
