Guanli Liu

I am a Postdoctoral Research Fellow at the University of Melbourne, working on AI for Databases, including spatial indexing, reinforcement learning-based query optimization, and LLM applications. My PhD research focused on learned spatial indexing, and has been published at top venues such as VLDB, ICDE, and TKDE. I am supervised by Dr. Jianzhong Qi and Prof. Lars Kulik.
Previously, I worked as a Senior Software Engineer at Baidu, and obtained my M.S. and B.Eng. degrees from Northeastern University, China.
