About Myself
I am a Senior Researcher at Tencent IEG Global, Visual AI team in Singapore, where I leverage 3D and multi-modal AI to automate and elevate game production workflows. I am also completing my PhD in Computer Science at the National University of Singapore (NUS) (thesis approved, oral defense pending), under the supervision of Assoc Prof Lee Gim Hee. My research focuses on 3D reconstruction, 3D generation, and high-efficiency rendering. I received my B.Eng in Computer Engineering from the Department of Computer Science and Faculty of Engineering at NUS in 2022, under the Science and Technology Scholarship.
I am a passionate researcher and innovator dedicated to bridging the gap between cutting-edge 3D vision research and real-world applications. During my Ph.D., I focused on 3D reconstruction and led an entrepreneurial initiative with my labmates to commercialize our technology for immersive navigation and 3D design through Mirror World. I firmly believe that mastering 3D representations is a vital stepping stone toward Artificial General Intelligence, and I am driven to advance how intelligent algorithms capture, understand, and generate our physical and virtual worlds.
Work Experience
