🔍Research interests

Human-Computer Interaction; LLM-augmented interface design for domain experts; Human-AI collaboration. My work advances the thesis that Interface design, not model capability, is the primary bottleneck for expert use of large language models, grounded in HCI theory (reification, distributed cognition, articulation work, boundary infrastructure).
