Hi! I'm exploring AI in New York, with a focus on making AI something the public shapes, not just uses. I'm also interested in how robotics becomes accessible to the general public, how it scales, and how humans and machines interact.

Before this I was at Goldman Sachs in the Global Industrials Group, covering industrial tech and advising Fortune 500 companies on $8B in M&A transactions. It taught me how to work fast, under pressure, with direct exposure to enterprise clients.

I studied economics and art history at Harvard. While there I built Dion Academy, a college admissions consulting business serving students across the US and China, and started making bilingual content about admissions, AI, and building things. I also help small businesses with hands-on AI transformation on the side.
