Jiawei Ren

I am an algorithm researcher at SenseTime Research (Singapore), where I work on computer vision and machine learning.

At Sensetime I've worked on Long-tailed Visual Recoginition, Panoptic Segmentation, Trajectory Prediction, and 3D Pose Estimation. Previously, I did my bachelors at Nanyang Technological University (NTU).
