Hi 👋 - I'm Joon, a researcher focused on making the world more accessible.

Ph.D. Student @ Carnegie Mellon University, Human-Computer Interaction Institute

I'm a second-year Ph.D. student at Carnegie Mellon University's School of Computer Science, advised by Patrick Carrington and Andrew Begel. I focus on understanding, designing, and building AI-equipped assistive technology (AT) and how such tools affect and alter existing social dynamics in intro- and extra-spective ways – tackling stigma, user-assimilation, and the AT adoption/abandonment problem through my research.
