Biography

I am a Research Scientist at Ropedia, Inc., and concurrently a visiting student at MMLab, Nanyang Technological University (NTU), advised by Prof. Ziwei Liu.

My research interests lie in 3D Vision, Embodied AI, and Multi-Modal Models.

Before that, I was a Research Intern at the LongCat Group, Meituan, Inc. (北斗人才计划), advised by Dr. Manyuan Zhang. I also worked as a research intern at StepFun Inc., led by Xuanyang Zhang and Dr. Gang Yu. From 2023 to 2024, I worked as a research intern at the Robotics Team, ByteDance AI Lab, under the mentorship of Minghan Qin. I also interned with the VIS at Baidu Inc., guided by Dr. Chenming Wu and Jingdong Wang (IEEE Fellow). In 2022 to 2023, I was a research intern at Zhejiang Lab, leading with Prof. Lechao Cheng.
