Youtian Lin 林尤添

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.

我目前就读于 南京大学，师从 姚遥教授，并在 曹汛教授 和 谭铁牛教授 的联合指导下攻读博士学位。此前曾在 哈尔滨工业大学 学习。2021年于 哈尔滨工程大学 获得硕士学位，导师为 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.

目前在 DreamTech 担任研究实习生。曾就职于顶尖的 3D 生成初创公司 Taichi（Meshy AI）和 VAST（Tripo AI），参与其早期 3D 生成技术的研发与突破。

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.

我的研究领域为计算机视觉与图形学，专注于3D和4D场景的重建与生成技术。同时深入探索神经渲染和生成式模型的前沿发展，致力于构建物理世界的真实数字表征。

I'm also interested in high-performance GPU and Graphic programming, including CUDA and Vulkan (also kind of knowing OpenGL and Metal).

同时热衷于高性能GPU计算和图形编程，熟悉CUDA、Vulkan等技术栈（亦掌握OpenGL和Metal开发）。
