I design for
behavior change
in high-stakes contexts.

From Harvard-founded analytics platforms to national EV charging networks, I've worked at the intersection of complex methodology and human adoption — making complicated systems feel simple.

Philosophy

Full bio →

Don't simplify the science.
Sequence access to it.

My work most recently sits at the intersection of rigorous systems and the humans who need to act on them. Whether that's a recruiter making a hiring decision, a police department auditing Use of Force data, an EV driver charging for the first time, or a Domino's employee taking 200 orders a shift.

Most design problems I've worked on aren't 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.
