Hi! Very briefly now:

I want to expand the reach of human knowledge and ability.

I’m a technologist, designer, and researcher focused on inventing tools and media which help us think. I’m presently independent, following five years at Khan Academy, where I led R&D, combining practices from product design, academic research, and pedagogy to explore new possibilities in education.

Previously, I helped make iOS at Apple with the UIKit team, made various open-source creative and engineering tools, prototyped creative tools at Panic, and studied computer science at Caltech.
