I design for behavior change in high-stakes contexts — making complex, rigorous systems legible and adoptable for the humans who need to act on them.

Background

I've been lucky to have worked across nearly every medium, screen size, and experience — from product design to illustration — and I'm still in love with the process! From designing products and websites for brands like HBO and the Rolling Stones to EV experience design with Electrify America to making rigorous data science legible at Sigma Squared.

Most design problems I've worked on aren't simply about aesthetics. They're about adoption. People won't use what they don't understand, and they won't trust what feels like a black box. Especially in the era of AI.
