About Me

Hi, I’m Guanghao Li, currently based in Shanghai, China.

I am interested in Robotics, specifically 3D reconstruction using differentiable rendering and Visual-Inertial SLAM (VI-SLAM). Looking ahead, I hope to expand my work into motion control and active exploration.

Outside the lab, I enjoy exploring the outdoors. I love taking road trips through uninhabited areas and climbing snow mountains, with a personal goal of traveling the world. I am also passionate about applying my research to these hobbies. By using low-cost vision and IMU sensors, I aim to achieve reliable trajectory recording, offline map matching, and even navigation in extreme outdoor environments.

Currently, I am preparing to climb Qizi Peak, the South/North slopes of Yuzhu Peak, and Mt. Jinyin.

I expect to graduate around 2027/2028 and am actively looking for Postdoc, Researcher, or Engineer positions. Maybe Alpine Guide / Expedition Leader is also suitable for me. Feel free to reach out.
