Biography

Hi! My name is Yixiang Fang. I received my Master Degree from Harbin Institute of Technology, China in 2013. Currently, I am a Ph.D. student in Database Group of Department of Computer Science, The University of Hong Kong, advised by Dr. Reynold Cheng. Here is my CV.


Research Interest

My research interest mainly focuses on big data analytics, especially on proximity queries. I am passionate about managing large-scale data with platforms like Hadoop and Spark. My current topics are summarized as follows:

  • Graph database: community, similarity, topic detection
  • Spatial database: trajectory, community, keyword search
