I am currently a final-year Master’s student in Artificial Intelligence at Fudan University (Sep. 2021 - Jun. 2024, expected), where Prof. Tao Chen is my advisor. I am also fortunate to work closely with Dr. Hongyuan Zhu from A*STAR, Singapore, and Dr. Gang Yu, Dr. Xin Chen, and Dr. Chi Zhang from Tencent. Before this, I obtained my Bachelor’s degree in Data Science and Big Data Technology also from Fudan University (Sep. 2017 - Jun. 2021).

My long-term research goal is to develop vision-language systems that can comprehend, reason, and envision the physical world.

📣 I am actively looking for researcher / Ph.D. opportunities. Please check out my resume here.
