I am a Research Scientist at NAVER AI Lab, leading the Human-Computer Interaction (HCI) Research Group. I design, develop, and evaluate Personal Informatics (PI) technologies that empower people to better learn about themselves and make positive changes in their behaviors and thoughts. Recently, I have investigated how we can leverage (generative) AIs for PI systems to acknowledge and account for the lifelong challenges of marginalized populations.
I am a recipient of International Postdoc Fellowship supported by National Research Foundation of Korea in 2019, a Best of CHI Honorable Mention award at CHI 2021, and a Best Paper award at CHI 2023.

Research Approaches
- Understand. To deeply comprehend user needs and expert practice, I conduct formative interviews and focus groups with domain experts and target populations.
- Design. Based on lessons learned from the formative study, I create engaging user experiences through hands-on design of visual interfaces, information architecture, and interaction patterns.
- Implement. I develop high-fidelity working prototypes that translate the designs into functional systems. I code across platforms using appropriate technologies to create robust implementations that support real-world evaluations.
- Evaluate. I evaluate the working prototypes through mixed-methods approaches including lab studies and in-the-wild deployments. My analysis combines qualitative techniques (thematic analysis) with quantitative measures to provide comprehensive insights into user experiences and system effectiveness.
