🙋 About Me

I am a PhD student at Department of Computer Science and Technology, Tsinghua University, advised by Prof. Wenwu Zhu and Prof. Xin Wang.

My interests lie in Multimodal Understanding & Generation, Embodied World Model, and Game Agent.

I received my B.Eng. from School of Materials Science and Engineering, Tsinghua University in 2022.

Feel free to call me Von or VonWei in any casual, non-ID-check situation — I’m perfectly fine with that. Just replacing “Feng” with the German word “Von”, since they share the same Chinese character 冯.

🎃 Interests

• ⚽️ Football
• 🏸 Badminton
• 🎮 Game Agent, I am currently a participant of 3DGameAgentBench

• 🃏 I am a huge fan of boardgames, including RPG games (Arkham Horror), actuarial games (Lost Ruins of Arnak, Great Western Trail), and party games (UNO, Avalon, Love Letter). I have organized/participated in online or offline boardgames with friends from but not limited to the following countries: 🇨🇳🇺🇸🇫🇷🇦🇺🇮🇩🇩🇪🇧🇷🇮🇹🇭🇺🇧🇪🇨🇦🇦🇷🇫🇮🇵🇱🇵🇹. I am also designing my own boardgames Yin Yang Scam（阴阳骗局） and Werewolf Scam（狼人骗局）, and will share progress once they are ready — looking forward to connecting with fellow enthusiasts!

  My boardgame preferences for games played in 2025

  

  夯：Excellent, 顶级：Very Good, 人上人：Good, NPC：Worth to play, 拉：Recommended to play only one or two times at most
