is designing
for social good

I’m a designer, UX researcher, writer, and armchair cognitive scientist. I currently work on Uber Health—a tool that lets healthcare organizations use Uber for non-emergency transportation. Previously, I studied cognitive science at Yale and designed products for Hillary Clinton’s 2016 presidential campaign. My work has been featured in NPR, Fortune, Quartz, and the Huffington Post.

Designing a dynamic journal

My computer recently informed me that I’ve typed over half a million words in my journal since 2013. This mind-bending stat got me thinking about what a digitally-native journal could be like—and what it could teach us about ourselves.

Ungluing from reality

A brief reflection on invisible assumptions and the wisdom of crowds (or lack thereof).

Algorithms to Live By


Think loopy, not linear.

Think in terms of feedback loops rather than linear journeys. Where did the user come from, where are they going, and who/what are they interacting with along the way?

Create with your users, not for them.

Good design is humble and participatory. Know your audience, and remember that you have a lot to learn from them.

Treat your process like a design project.

Think not just about what you’re doing, but how you’re doing it. Always ask how you can be a tiny bit better next week. Small changes compound.

Share stories, not static screens.

Design around people’s goals rather than arbitrary lists of features. Understand the story about what they’re trying to accomplish and why. You’ll make better decisions when your ideas are interactive.

Design is content is design.

Kill your lorem ipsum—copy is an integral part of design. Use real content and data when you design, and remember to account for the worst case scenarios.
