Hi! I am a Ph.D. student in the computer science department at Columbia University, advised by Brian A. Smith in the Computer-Enabled Abilities Lab (CEAL).


Research: AI-Driven Interactive Systems

I design, build, and study AI-driven interactive systems that apply existing AI techniques in creative ways to grant people new abilities. My research revolves around developing systems that address accessibility problems, with a focus on improving access to visual experiences for people with visual impairments.

Using my systems, blind and low-vision (BLV) people can visualize the action in sports broadcasts for themselves rather than relying on other people’s descriptions (CHI 2023, UIST 2023). My systems embed AI within street intersections to give BLV people the ability to interact with street cameras for safe outdoor navigation (ASSETS 2023, arXiv 2023).

To inform future systems, I also conduct qualitative studies aimed at understanding people's needs. In my recent work, I introduced the concept of "exploration assistance systems," that give BLV people the freedom to explore unfamiliar environments on their own, rather than being guided by turn-by-turn instructions (CSCW 2023). This paper received an Impact Recognition Award 🏆.
