I travel. I take photos and videos. I run. I believe great stories happen to those who can tell them.
I'm a researcher, content creator, and contributor. Building off an education in computer science and a background in corporate finance, I've created educational resources about Ethereum, host podcasts, and built communities around decentralized technology.
I also believe that Ethereum is the world computer—a globally shared piece of technology that will make the world more open, fair, and trustworthy.
Creative
Photos and videos let us travel back in time. They let us re-experience the best moments of life. I capture everything on my iPhone (and occasionally a GoPro or drone).

In November 2016, as I was packing up to head home from work, I downloaded Couch to 5K and resolved to get started that night. Six months later I'd lost 100 pounds and finished a half marathon. Six months after that, I ran the New York Marathon in 3:35.
Since that first run in 2016, I've logged thousands of miles across 42+ countries. These days I make a point of running long distances wherever I am. I've experienced everywhere in a completely new way.
Each mile tells a story.
