Welcome
Since 2014, I have been a Ph.D. student in College of Optical Science and Engineering at Zhejiang University with the major in Instrument and Meter Engineering and a researcher at State Key Laboratory of Modern Optical Instrumentation. I received the B.S. degree in Measurement Technology and Instrumentation from Beijing Institute of Technology and the dual degree in Economics from Peking University.

Currently I'm a joint training Ph.D. student in Wangkaiwei Team advised by Prof. Kaiwei Wang and Prof. Jian Bai at Zhejiang University, and RobeSafe Research Group at University of Alcalá advised by Prof. Luis Miguel Bergasa.

Startup
I am the Co-founder and Chief Technology Officier at Hangzhou KR-VISION Technology Co., Ltd, a company dedicates to developing assistive technology for the visually impaired. I am also the Co-founder and Chief Technology Officier at Hangzhou SUR-IMAGE Techonology Co., Ltd, a startup with the aim to develop multi-modal stereo vision sensor for upper-level applications.

Research
I am interested in real-time computer vision with the goal of developing assistive technologies for autonomous driving, robotics and wearable systems to assist real-world navigation of vulnerable road users and visually impaired pedestrians.
My main research over the past few years has been on stereo vision, traversable area detection, semantic segmentation, depth estimation, polarization imaging, panoramic annular lens, sensor fusion and obstacle avoidance.
Broadly I am interested in computer vision, 3D vision, deep learning, optics, robotics, assistive technology and intelligent vehicles.
