Brief Biography

I am Xuanhe Zhou, a Ph.D. candidate in CS of Tsinghua, mentored by Prof. Guoliang Li. My research interest lies in autonomous databases, i.e., automating and optimizing the logical/physical designs of databases so as to better serve AI/DB users. I have published 10+ papers in SIGMOD/VLDB/ICDE conferences and 2 surveys in TKDE (700+ citations in total). I have led several open projects, e.g., openGauss-dbmind, febench, dbgpt (d-bot). My works have been applied in enterprises like 4Paradigm and Intel. Honors include VLDB Best Industry Paper Runner-up (first author), Microsoft Scholar, Tsinghua Outstanding Scholarship, etc.
周煊赫，清华大学计算机系博士，师从李国良教授，专攻自治数据库系统，即自动化数据库系统的逻辑和物理设计。发表顶级数据库论文10余篇，引用700余次。主导多个开源项目，如 openGauss-dbmind、febench、dbgpt (d-bot) 。 成果在邮储、工行、第四范式、英特尔等重要企业应用。曾获 VLDB最佳工业论文提名、微软学者、清华特奖等荣誉。

Research Directions

The relevant research problems include but are not limited to :
(1) Database Optimization (e.g., query rewrite);
(2) Database Configuration (e.g., parameter/index/partition);
(3) System Diagnosis (e.g., root cause analysis);
(4) AI-relevant Techniques. I also explore interesting AI techniques that can benefit above aspects (e.g., online feature store, tool4LLM, multi-LLM).

Open Projects

One of our current targets is to open-source a series of practical, out-of-the-box tools (outside/inside database kernels) for both AI and DB users with my excellent collaborators, e.g.,
An LLM-based database administrator that can acquire database maintenance experience from textual sources, and provide reasonable, well-founded, in-time diagnosis advice for databases.
https://github.com/TsinghuaDatabaseGroup/DB-GPT
A novel benchmark specifically designed for real-time feature extraction (RTFE) within the domain of online AI inference services. These services are rapidly being deployed in diverse applications, including finance, retail, manufacturing, energy, media, and etc.
https://github.com/decis-bench/febench
Full-process autonomous database operation and maintenance capabilities, e.g., slow SQL root cause analysis, workload index recommendation, multi-metric correlation mining, fault self-repair, anomaly detection and root cause analysis, and etc.
