# DaEun Choi

> Ph.D. student in HCI at KAIST (KIXLAB). Research on generative AI systems that support human creativity.

I am a 3rd-year Ph.D. student in the School of Computing at KAIST, working with Prof. Juho Kim at KIXLAB. I interned at Adobe Research in summer 2025 and at Autodesk Research in summer 2026.

My research interest is in Human-Computer Interaction (HCI). I design interactions for generative AI systems that support human creativity by enabling the expression, reuse, and evolution of ideas across diverse creative processes.
