I am Huajie Tan (谭桦杰), a third-year M.S. student at the School of Computer Science, Peking University, advised by Prof. Shanghang Zhang. Previously, I received my dual-degree B.Eng. from Tianjin University (College of Intelligence and Computing & College of Microelectronics) and was honored with the Outstanding Graduate Award.
My research focuses on embodied AI and multi-modal foundation models. I am currently an intern at the Beijing Academy of Artificial Intelligence (BAAI), exploring pathways toward general-purpose robotic intelligence and real-world deployment of embodied systems. I am also open to collaborative opportunities and research partnerships, feel free to email me: tanhuajie@stu.pku.edu.cn.
Meanwhile, I am now seeking entrepreneurship opportunities. I have received multiple top-tier offers from leading industry labs, e.g., Huawei Top Minds (华为天少), Tencent QingYun (腾讯青云), JD Tech Genius Team (京东TGT), BAAI Star (智源智星) and Xiaomi Top Talent (小米顶尖计划). If you have a better fit or would like to connect, please also feel free to reach out.
