Lei Sun (孙磊)

I am a doctoral student at Zhejiang University under the supervision of Prof. Kaiwei Wang . I am also a visiting doctoral student at Computer Vision Lab, ETH Zurich under the supervision of Prof. Luc Van Gool. Before that, I received my bachelor's degree from Beijing Institute of Technology.

I am looking for post-doc positions or job opportunities related to event camera, low-level image process, and environment perception algorithms.
