Kai Han韩 锴 Postdoctoral Researcher |
I am Postdoc in the Department of Engineering Science at the University of Oxford, working with Prof. Andrew Zisserman and Prof. Andrea Vedaldi. I received my Ph.D. degree in Department of Computer Science at The University of Hong Kong under the advisement of Prof. Kenneth K.Y. Wong in 2018. I was a Research Intern at the WILLOW group (INRIA / École Normale Supérieure, Paris, France) working with Prof. Jean Ponce and Prof. Minsu Cho in 2016. Previously, I received my M.Eng. from Harbin Institute of Technology in 2014 and B.Eng. from Harbin Engineering University in 2011.
