About Me

I am a 3rd-year PhD student (expected to graduate in 2029) at the University of Science and Technology of China, supervised by Prof. Yu Qiao. I also work closely with Shanghai AI Laboratory, advised by Dr. Yi Wang and Prof. Limin Wang, where I contribute to the InternVideo series foundation models and work on video understanding.

Before that, I received my B.Eng. from the University of Electronic Science and Technology of China, ranking 1/121 in my major as an Outstanding Graduate.

I am actively looking for new internships in industry, feel free to reach out me! 😄

Off the Clock

I am a die-hard fan of Arsenal ❤️🤍 and Los Angeles Lakers 💜💛 for over a decade. Which means I have spent years training on long sequences of hope, heartbreak and late comebacks, a bittersweet lesson in patience, resilience, and keeping the faith.
