Ruijie Ren

Ruijie Ren is a Ph.D. Student at Waseda University (早稲田大学) supervised by Prof. Edgar Simo-Serra. He obtained a Master's degree in Autonomous Systems at Technical University of Denmark (DTU) under the supervision of Prof. Jeppe Revall Frisvad. In 2020, he obtained a Bachelor's degree with first class honours in Mechanical Engineering from University of Leeds.

He was very fortunate to have worked as a Research Assistant at Visual Intelligence Lab, Nanyang Technological University supervised by Prof. Shijian Lu in Computer Vision and Domain Adaptation. In 2021, he joined Perception and Manipulation Group in IRI (CSIC-UPC) and worked in Robotic Perception and 3D Reconstruction with Prof. Francesc Moreno-Noguer and Prof. Krystian Mikolajczyk. During his undergraduate study, he focused on Epidemic Dynamics and Multi-agent Systems under supervision of Prof. Ji Liu.

Research


My research interests span the fields of Robotics and Computer Vision, particularly visual odometry, object detection, 3d reconstruction, representation learning and domain adaptation.

I am open to research discussion and collabration, please feel free to contact me by email :)
