Research focus: machine learning for data systems · learned query optimization · database systems · AI systems
保护项 3 的预审审核：构建基于 learned query optimization、AI systems、database systems、reinforcement learning for systems 的拟合参数图，并整合隐私保护的数据集成；引用一个可见的实验室主题、校友/就业模式、基准信号、当前学生名单、招募/状态警告或项目领域，并提出一项具体的第一学期研究扩展。
Who this advisor fits / 什么情况下适合你
- Industry research or startup/translation paths appeal to you (meaningful share in public outcomes).
- Strongest applicant signal is systems background plus ML-for-databases specificity; early alumni evidence is useful but not yet a mature PhD placement tree.
- 工业研究或创业/转化路径对你有吸引力（公开去向里占比不低）。
- 最强申请人信号在于系统背景，并辅以 ML 对数据库的特定性；而 earl 的校友证据虽具参考价值，但尚未成熟地构建 PhD 的放置树。
What to watch for / 什么情况下要慎重
- Faculty-only is your sole goal and you want zero industry/translation exposure.
- 你把「教职为唯一目标」且完全不想碰工业/转化网络。
