Research Topics
  • Multi-Modal Sensors Calibration
  • Multi-Modal Perception
  • 3D Reconstruction
  • Scene Understanding

I am currently an Associate Professor (Tenured) of International School of Information Science and Engineering at Dalian University of Technology (DUT) . Before joining DUT, I was a researcher at Artificial Intelligence Research Center (AIRC) of AIST from 2018 to 2021. I received the Ph.D. degree from Nagoya University in 2017, an M.Sc. degree from Osaka University in 2012 and a Bachelor degree from Shanghai Jiao Tong University (SJTU) in 2009. I am also a Guest Researcher of AIRC since 2022 and a Guest Associate Professor of Ritsumeikan University since 2022.

I research machine perception, scene understanding and interaction from different scales of the 3D physical world using multimodal sensor data (Camera images, LiDAR 3D point clouds, Radar scans, etc.), aiming to enable machines to see the world in super vision.
