Toni Sagristà Sellés

I’m an informatics engineer specializing in scientific visualization and computer graphics, currently working on the ESA Gaia mission. I hold a Ph.D. in Scientific Visualization and Astronomy and an M.Sc. in Astrophysics, Particle Physics and Cosmology. Currently, my main project is the 3D Universe software Gaia Sky.

Outside of work, I’m fascinated by local LLMs and AI agents, and I spend my free time playing football, doing photography, and building things—like my Game Boy emulator, Play Kid. I also enjoy snowboarding, drawing (terribly), and playing with my kids.

I share more about these projects and my experiments in the blog.
