Kunyi Li

I'm a Ph.D student at the Chair of CAMP, Technical University of Munich, supervised by Dr. Federico Tombari. My research focuses on 3D vision, with a particular emphasis on SLAM, 3D scene reconstruction and understanding. I am also collaborating with Dr. Michael Niemeyer on related projects. In 2022, I obtained my Master's degree at Tsinghua University, where I focused on light field imaging and reconstruction. In 2019, I received dual Bachelor's degrees at Peking University.

For any inquiries, feel free to reach out to me via mail.
