Research Interest
My research focuses on building domain-specialized AI agents that reliably perform complex tasks in real-world settings. I am particularly interested in the core modules that make such agents work — harness engineering, orchestration, memory, retrieval, and multi-agent — and in how these components can be integrated into a coherent system. Recently, I have begun working on physical foundation models and the engineering systems around them. By combining my prior experience in agentic systems with this work on physical models, I aim to build an agentic robot framework that grounds these capabilities in physical interaction.
