Brief Introduction简介
I am a first-year Ph.D. student at Nanjing University, supervised by Prof. Yao Yao, Prof. Xun Cao and Prof. Tieniu Tan. Previously, I pursued a Ph.D. at the Harbin Institute of Technology. I earned my M.S. from the Harbin Engineering University in 2021, where I was advised by Prof. Jian Guan.
我目前是 南京大学 博士一年级学生，导师为 姚遥教授， 并由曹汛教授和 谭铁牛教授联合指导。之前在 哈尔滨工业大学 攻读博士学位。2021 年获得 哈尔滨工程大学 硕士学位，导师关健教授。
I’m currently a research intern at DreamTech. Previously, I worked at leading 3D generation startups Taichi (Meshy AI) and VAST (Tripo AI), where I contributed to their early 3D generation breakthroughs.
我目前是 DreamTech 的研究实习生。此前，我曾在领先的 3D 生成初创公司 Taichi（Meshy AI）和 VAST（Tripo AI）工作，参与并推动了它们早期在 3D 生成方面的技术突破。
Research Interests研究方向
My research interests are in computer vision and graphics, with a particular focus on 3D and 4D reconstruction and generation. I am also exploring recent advances in neural rendering and generative models. My work aims to reconstruct and synthesize realistic representations of the physical world.
我的研究兴趣主要集中在计算机视觉与图形学，特别关注3D和4D的重建与生成。我还在探索神经渲染和生成模型的最新进展。我的研究致力于重建和合成物理世界的真实表征。
I'm also interested in high-performance GPU and Graphic programming, including CUDA and Vulkan (also kind of knowing OpenGL and Metal).
我也对高性能 GPU 和图形编程感兴趣，包括 CUDA 和 Vulkan（也了解 OpenGL 和 Metal）。
