About Me

My research lies at the intersection of Data Systems and Artificial Intelligence. I build intelligent data systems that transform raw system telemetry and AI-generated traces into structured knowledge for reliable AI reasoning and lifelong system learning.

I am fortunate to be advised by Prof. Elke Rundensteiner, a leading researcher in data management and the founding head of the Data Science Department at WPI.

I am a member of the DAISY (DAta-Driven Intelligent SYstems) Lab, where we study scalable data analytics and AI-driven system intelligence.

My research interests include:

  • Reliable and Explainable AI Systems
  • Multi-Agent Systems and Lifelong Learning
  • Intelligent Data Systems for System Telemetry
