Yiming Qiao

I received my Ph.D. in Computer Science at the Institute for Interdisciplinary Information Sciences (IIIS), Tsinghua University, where I was advised by Prof. Huanchen Zhang. I also visited Centrum Wiskunde & Informatica (CWI) in the Netherlands, where I worked with Prof. Peter Boncz. My research focuses on database management systems, particularly query execution engines, query optimization, and data compression. I received my B.Eng. from Nanjing University of Posts and Telecommunications in 2021.

My current work spans robust query processing and databases for agents. Building on the Yannakakis algorithm, our RPT+ work combines query optimization and execution to make performance less sensitive to join order. I also explore how analytical databases and cloud services can support agents in storing, querying, and analyzing data.
