## About

I am currently a final-year undergraduate student at [Nanyang Technological University](https://www.ntu.edu.sg/), specializing in [Data Science and Artificial Intelligence](https://www.ntu.edu.sg/education/undergraduate-programme/bachelor-of-science-in-data-science-artificial-intelligence).

I am currently conducting research at [SenseTime](https://www.sensetime.com/en) and [MMLab@NTU](https://www.mmlab-ntu.com/). I am fortunate to be supervised by [Prof. Ziwei Liu](https://liuziwei7.github.io/), I am also grateful for the extensive help I have received from [Bo Li](https://brianboli.com/), [Yuanhan Zhang](https://zhangyuanhan-ai.github.io/), [Zhongang Cai](https://caizhongang.com/) and [Lei Yang](https://scholar.google.com/citations?user=jZH2IPYAAAAJ). My research interests center on multimodal models.

During my time at [Shaoxing No.1 High School](http://www.sxyz.net/), I participated in the [Olympiad in Informatics](https://www.noi.cn/). After graduating, I spent a rewarding year at the [International School of Information Science & Engineering](https://drise.dlut.edu.cn/) at [Dalian University of Technology](https://www.dlut.edu.cn/). During the COVID-19 pandemic, I chose to withdraw and begin my undergraduate studies anew at Nanyang Technological University.

I competed in the [ICPC](https://icpc.global/) at both universities. I also contribute to the [Nanyang Programming Contest](https://ntu-icpc.github.io/npc/). I am grateful to [my teammates and friends](https://pufanyi.com/icpc) for their support! 🙏

I enjoy playing chess. My Lichess username is [@pufanyi](https://lichess.org/@/pufanyi), and my current rapid rating is 2086.
