Gyuna Kim (κΉ€κ·œλ‚˜)

Digital Health and HCI Researcher

Daejeon, Republic of Korea

Hi everyone! πŸ‘‹

I am a master's student at KAIST ICLab, advised by Prof. Uichin Lee. My research spans various areas of digital health β€” from modeling human states using multimodal data, to enhancing the quality of physiological signals, and designing evaluative tools. While the specific topics differ, they all share a common goal: leveraging everyday data and technology to support better health outcomes. Ultimately, I aim to help build systems that make digital health support more effective, interpretable, and adaptable across different contexts.
