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.
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.
🫶 My Myers–Briggs Type Indicator (MBTI) is ENFJ (Extraversion-iNtuition-Feeling-Judging).
