Introduction

I am a Graduate Student Researcher at KAIST (Rise Lab), advised by Prof. Kimin Lee. My research lies at the intersection of Physical AI and Human-Computer Interaction (HCI).

Previously, I was a founding member of Polariant, where I developed novel polarization-based positioning technology that led to the company's acquisition by SOCAR. I subsequently engineered large-scale IoT systems at SOCAR and designed cloud architectures for Hi-Tech enterprises as a Solutions Architect at AWS.

Currently, I aim to develop proactive agents embedded in smart glasses and robots. I explore how these agents can utilize egocentric perception to understand user context and provide adaptive support, leveraging my industrial scalability experience to build robust AI for the real world.
