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.
