Hi! I am Zhengyu Hu🤗

I am an M.Phil. student (2023.9 – Present) at the Hong Kong University of Science and Technology, Guangzhou, where I am fortunate to be advised by Prof. Hui Xiong.

Research Interests: My current research interests are Data-Centric AI/ML, particularly in the evaluation, alignment, and agent applications of LLMs and VLMs.

😎 Hobbies

I’m really into sandbox games, especially Terraria! It’s an incredibly fun game where you can explore and create freely. If you’re curious to learn more about it, you can check out the Terraria Wiki for detailed information.

My dream is to travel around the world one day!
