Hello!😊 I’m a second-year PhD candidate of Harbin Institute of Technology, majoring in Computer Science, at Computing Faculty.

My research interests includes Multi-modal, Multi-lingual and Chain-of-Thought Reasoning. If you are seeking any form of academic cooperation, please feel free to email me at charleschen2333@gmail.com.

Currently, I am a PhD at SCIR supervised by Prof. Wanxiang Che and Prof. Libo Qin. Previously, as a master’s student, I have done research intern at Shanghai AI Laboratory , supervised by Dr. Zhi Chen. As an undergraduate student, I have done research intern at Baidu NLP , supervised by Lijie Wang and Dr. Jing Liu.

Other than my work, I’m honored as Deputy Secretary-General for MLNLP community and Member of the Presidium of the Student Union of the Department of Computing, Harbin Institute of Technology. Previously, I was the president of HIT Software Competition Club from 2021 to 2023.
