I build human-centric language technologies, focusing on cognitively aligning human and machine thinking, advancing AI as thinking partners. My work bridges language and cognition to develop novel algorithms, benchmarks, and interaction frameworks that support experts in complex, real-world cognitive workflows.

I design AI that augments humans: models that learn from how people plan, reason, and create; anticipate cognitive bottlenecks; scaffold difficult tasks; and adapt dynamically to expert strategies. See my research statement (technical, non-technical). My current research focuses on three areas:

• Cognitive scaffolding: Assessing LLM cognition compared to human and enhacing their cognitive capabilities like planning, compositionality, and reasoning.
