About

Dario Loi — **The author.** Thinking about sheaves, probably.

I started my Ph.D. in Computer Engineering at Northeastern University in Boston in September 2026. I work on machine learning in the Mentis Laboratory.

Before Northeastern I studied at Sapienza University of Rome, where I earned a B.S. in Applied Computer Science and Artificial Intelligence with full honors and an M.S. in Computer Science. I also build Polytope, the design system this site runs on.
