About me
I will be a Assistant Professor at Soochow Uniersity, before that I received my Ph.D degree at Shanghai Jiao Tong University. and I received my Master's degree from Nanjing University of Posts and Telecommunications. My current research focuses on large language models, on-policy distillation, and efficient multimodal reasoning.
I study reliable and efficient multimodal intelligence, with a particular interest in understanding how visual information is represented, propagated, and degraded during complex reasoning.
For research discussions or potential collaborations, please feel free to contact me via SemiZxf@163.com.
