Welcome to Xiaopeng Zhang's Homepage

I am currently a Senior Researcher at Huawei Noah's Ark Lab, Shanghai. Before that, I was a Research Fellow from 2017 to 2019 with the Department of Electrical and Computer Engineering at National University of Singapore, a member of Learning and Vision Lab under the supervision of Jiashi Feng and Shuicheng Yan. I finished my PhD in Electronic Engineering from Shanghai Jiao Tong University in 2017, under the supervision of Pro.  Hongkai Xiong and Pro.  Qi Tian.  My research interests are focused on computer vision and machine learning. Now I am leading a computer vision research team in Noah Ark Lab, working on 2D/3D detection related problems in autonomous driving.

I am always recruiting highly motivated interns (PhD preferred) focusing on data efficient and  engery effieient 2D/3D detection, scopes include (but not limited to) self-supervised learning, multi-modal learning, network optimization, data augmentation etc. We offer sufficient computing resouces and competive benefits. if you are interested, please drop me an email.
