I design systems that help people think — making information more accessible, more navigable, and more useful.

Currently

I’m a Senior Research Scientist at Adobe Research specializing in Human-Computer Interaction (HCI). I study how people make sense of complex information and design technology that can meaningfully support that process. My work was recognized with Adobe’s Tech Excellence Award for my contributions to AI product development and evaluation.

Previously

I completed my PhD at Stanford University’s shape lab and HCI Group , where I built accessible tools for people with disabilities — making information perceivable through touch, sound, and other modalities. I’ve also worked at Microsoft Research and HP Labs. Watch an interview showcasing my work.

At Stanford, I taught courses on design thinking, accessibility, and smart product design. My research was featured in Fast Company , TechCrunch , The Wall Street Journal , Gizmodo , Core77 , and the National Science Foundation’s Science Now series.
