About Me

I am currently a LLM Algorithm Engineer at Tencent Yuanbao focus on post training. In previous, I was a PostDoc at Duke Kunshan University, reporting to Prof. Kaizhu Huang. I obtained my Ph.D. from the University of Liverpool in July 2025, supervised by Prof. Qiufeng Wang, Prof. Kaizhu Huang and Prof. Xiaowei Huang. Also welcome to check my bilibili.

  1. Embodied Model Application
    Parcel Grasping for Humanoid Robots
    2025.11 - 2025.12
    Collaborated with FiveAges. Based on the Unitree G1, implemented an end-to-end frame-work for autonomous parcel identification, grasping, and placement. Responsible for training and optimizing the NVIDIA GR00T N1.5 model using teleoperation data and deploying it via SDK on G1.
