Zlin’s Extraordinary Research Oasis

Zeal, Excellence, Reliability and Openness

Welcome to the ZERO Lab, the research group lead by Prof. Zhouchen Lin (Zlin), affiliated to School of Electronics Engineering and Computer Science, Peking University. We research on machine learning and computer vision.


  • Our group at Peking University is recruiting tenure-track faculties and PostDocs (academic or industrial). For the postdoc program in 2020, please refer to the Chinese version or the English version.
  • Our group at Peking University is recruiting Ph.D.s who have strong mathematical abilities (however, this does not imply that you have to come from mathematics department) and great interest in theoretical analysis in order to enjoy with me how to use mathematics to solve real problems elegantly.
  • Our group at Peking University is also recruiting Masters who have strong coding skills and interests in Quantitative Trading (a reference book). Welcome to send me your detailed resume!
  • Our group at Zhijiang LAB is recruiting Researchers and PostDocs.
  • Samsung AI Lab is recruiting top-caliber researchers with strong expertise in machine learning!
