Short Bio

  I am a PhD candidate in Computer Science at the University of Auckland. My current research focuses on relational databases and anomaly detection from system logs.
  Specifically, my work mainly consists of the following areas:

• Schema Design Optimization: Developing novel normalization algorithms to minimize data redundancy and improve update efficiency while preserving functional dependencies.
• Update Cost Reduction: Quantifying the trade-offs between normalization levels and update overheads in database systems.
• Mining FDs/Keys from Data: Mining meaningful Functional Dependencies/Keys from data with domain expert knowledge.
• Detecting Anomalies from System Logs: Mining anomalous patterns from system logs to find root causes via deep learning techniques.

If you are interested in exploring possible collaborations, please don’t hesitate to reach out.
