Research Interests

I study Human-Centered AI at the intersection of NLP, IR, and HCI. My research examines how AI shapes human cognition and behavior, with the goal of improving models and systems to strengthen human capabilities and support responsible and safe use.

Human–AI Interaction

Understanding how AI interactions shape human cognition, judgment, and collaborative performance.

Model Evaluation & Alignment

Evaluating model capabilities and behavior, and developing approaches to align AI systems with human goals and needs.

Responsible & Safe AI

Identifying and mitigating AI risks to support human agency and responsible, safe development and use.
