arXiv preprint (*Equal contribution)
I am an M.S. student at the Mobile Intelligence & Interaction Lab at KAIST, advised by Prof. Sung-Ju Lee. I received my B.S. in Data Science from Hanyang University and studied as an exchange student at Universidad Carlos III de Madrid. Previously, I worked as an intern at Samsung Electronics DS AI Center.
My research focuses on digital healthcare, human-computer interaction, and human-centered AI. I currently work on mobile sensing for digital healthcare and am interested in designing intervention systems that provide timely and meaningful support in everyday life.
Research Interests: Digital Healthcare, Human-Computer Interaction, Human-Centered AI
