Hello! I am a PhD Candidate at Stony Brook University (New York), advised by Dr. Arie E. Kaufman.
I am an interdisciplinary researcher in visualization and applied AI, specializing in context-aware interfaces.
My research combines visual computing and embodied interaction to support people across desktop, mobile, and XR environments.
I develop LLM agents that use structured representations of user activity and environmental context (e.g., scene graphs, spatial memory, and interaction history) to interpret user intent and provide context-sensitive agentic assistance,
so that interactive systems can "understand" users and their situations and "adapt" their responses accordingly.
I see myself as an applied "systems" researcher. I ground interface design in elicited domain needs, develop functional prototypes, and use mixed-method evaluation (controlled, diary, and in-the-wild studies) to examine usability and refine interaction workflows.
This approach runs through my work on wearable AI agents for spatial media authoring, everyday wearable AR assistance, AI-assisted visual analytics of recorded XR activity, and scientific visualization for domain experts on large-scale displays.
I am particularly interested in bridging emerging AI capabilities with human-centered interaction to create experiences that adapt across users, devices, and computing contexts, and I enjoy interdisciplinary collaboration with creators, domain scientists, and industry partners.
I actively contribute to the XR, Visualization, and HCI research communities.
Prior to my PhD journey, I received my master's degree from Stony Brook University in 2020, where I also had the opportunity to conduct research under the supervision of Dr. Xiaojun Bi. I received my bachelor's degree from Soongsil University, South Korea, in 2017.
