About Me
I am an Assistant Professor at Soochow University. Before that, I received my Ph.D. degree from Shanghai Jiao Tong University and 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 am currently collaborating closely with Prof. Min Zhang (ACL Fellow) and Prof. Juntao Li at Soochow University on large language models and multimodal intelligence.
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.
