About me
I am a Ph.D. student of Nanjing University of Aeronautics and Astronautics, supervised by Qingshan Liu. Before, I served as an algorithm engineer of Leapmotor Technology from July 2021 to February 2023. I obtained my Master's Degree and Bachelor's Degree at Nanjing University of Information Science and Technology respectively, supervised by Qingshan Liu. My current research is mainly focus on general 3D perception, including segmentation and detection for point cloud. Here is my personal CV.
