Bo Tang received the PhD Degree in the Department of Computing at Hong Kong Polytechnic University. He was a member of Database Research Group. He was supervised by Dr. Ken Yiu. He was a visiting researcher at MonetDB group (Amsterdam) and Microsoft Research Asia (Beijing). Before that, he obtained his BEng degree in computer science from Sichuan University.


Research Statement

My research interests are in the area of data management (i.e., database/big-data systems, query processing). In particular, I focus on improving query time efficiency and data analytical result accuracy. I do research because I really enjoy it. Especially, I want to do top research work which will make a difference to our life.
