I am Chengliang Chai (柴成亮 in Chinese), currently a Postdoc researcher in the Dept. of Computer Science and Technology, Tsinghua University. I am a member of Database Group of Tsinghua and under the supervision of Prof. Guoliang Li. Before that, I received my PH.D. from Tsinghua Universitity 2020 and I completed my B.S. in 2015 at the the Harbin Institute of Technology.
My research missions are from two aspects. One is to leverage data management techniques to benefit AI, including data cleaning, data discovery and labeling. The other is to utilize AI to improve the database performance, including the learned optimizer, learned index and database tunner.
