Human Factors Researcher @ UMich
I envision the design of trustworthy human-AI collaborations that preserve and promote the positive values unique to human society. My research seeks to understand trust formation, evolution, and behavioral dynamics in complex teaming situations, drawing on traditional trust and psychology theories and examining how they translate into human-AI interaction. Building on these insights, I perform user segmentation and predictive modeling of trust and behavior, with the ultimate goal of designing trust- and behavior-aware AI that can foster more effective teamwork.

My name is pronounced Hey-sun, like greeting the sun ☀️☀️☀️ 😉!
Thanks to the incredible support I've received throughout my academic journey, I am honored to have recently been named a Barbour Scholar, awarded to selected recipients of the Rackham Predoctoral Fellowship. Also, I am grateful to be a recipient of the Kwanjeong Educational Foundation Study Abroad Scholarship, awarded through a nationwide selection process in South Korea.
Exciting news from the 2025 ASPIRE HFES International Annual Meeting!
I am happy to share that I have been awarded the Student Member with Honors Award. In addition, one of my accepted papers ("Trust in the Team as a Function of Trust in Individual Agents: Scale Validation and Modeling") received the Best Student Paper Award from the K-HFES Awards Committee.

Dissertation Title: From Dyadic to Multi-Agent Human-Autonomy Interaction, Exploring Trust Dynamics and Human Behaviors
Since joining ICRL (Interaction and Collaboration Research Lab) directed by Dr. X. Jessie Yang, I have been deeply involved in applying computational and data science methods to model human trust and behaviors in human-AI interaction and collaboration. My primary focus is on multi-agent human-autonomy interaction (HAI), which involves multiple humans and/or intelligent agents collaborating toward a shared goal, such as defense, crowdsourced evacuation, and search-and-deliver tasks. My core research questions include:
-
How can team metrics (e.g., team trust, team communication effectiveness) be defined and quantified?
-
How do the behaviors and attitudes of others influence an individual's behavior and attitudes?
-
How can we predict the real-time trust and behavioral dynamics?
-
How can we promote and encourage human prosocial and altruism behaviors in HAI?

During my undergraduate and master's studies, I led and participated in numerous exciting projects that are fundamentally aimed at enhancing the user experience of products, services, and systems across various domains (e.g., self-service technology, transportation, mobile, AR/VR, etc.) through end-user data analysis and empirical research. Leveraging my unique interdisciplinary background in engineering, design, and business, I contributed to core project activities, which holistically encompass all phases of UX design: designing, prototyping, evaluating, and conducting data-driven analyses.
