Curriculum Vitae

Wan-lei Zhao received his Bachelor degree of Eng. and Master degree of Eng. from Yunnan University, China in Jul. 2002, Nov. 2005 respectively. During his graduate study, he was with Software Institute of Chinese Academy as an exchange student from Oct. 2003 to Oct. 2004. During that period, his research focus was on optimizing clustering approaches such as k-means and Mean-shift. During the PhD study, he was under the supervision of Prof. Chong-Wah Ngo, his research focus is on large-scale near-duplicate video detection. He received PhD degree on Nov. 2010 from City University of Hong Kong.

    He worked at University of Kaiserslautern, Germany from Feb. 2011 to Jun. 2012 as a post-doc. During this period, he was under the supervision of Dr. Prof. Thomas M. Breuel. From Jul. 2012 to Dec. 2013, he was with INRIA, France as a post-doc, under the supervision of Dr. Herve Jegou and Dr. Gravier Guillaume. His current research focus is multimedia information retrieval.

I have one post-doc enrollment quota, I am looking for talented young researcher who receives his/her Ph.D degree in computer science before July 2025. Please send email to Dr. Zhao if you are interested. For details of the enrollment, please check the HR website of Xiamen University.
