Wenzhao Zheng

I am currently a postdoctoral fellow in the Department of EECS at University of California, Berkeley, affiliated with Berkeley Artificial Intelligence Research Lab (BAIR) and Berkeley Deep Drive (BDD) , supervised by Prof. Kurt Keutzer . Prior to that, I received my Ph.D degree from the Department of Automation at Tsinghua University, advised by Prof. Jie Zhou and Prof. Jiwen Lu . In 2018, I received my BS degree from the Department of Physics, Tsinghua University.

I am interested in computer vision and deep learning. My current research focuses on:

  • Vision-centric autonomous driving that efficiently perceives and predicts the complex 3D world based on images.
  • Omni-supervised representation learning that exploits various types of supervision signals to learn discriminative and generalizable visual representations.
  • Explainable artificial intelligence that builds comprehensible and trustworthy AI systems with high performance.
  • If you want to work with me (in person or remotely) as an intern at BAIR, feel free to drop me an email at wzzheng@berkeley.edu.
