Hola,  I am Sergio Alejandro fernandez de soto guerrero!

I'm a mathematician specializing in combinatorics and discrete geometry, with a particular interest in the mathematical foundations of magic and recreational mathematics. Online, I create scientific content under the name Sergio Matemago.

I'm currently a PhD student at the Institute of Geometry at TU Graz , under the supervision of Cesar Ceballos, and a member of the PAGCAP research group. I completed my master's degree at the Universidad del Valle, where I worked under the supervision of Rafael Gonzáles D'León.

My research interests include combinatorics, polytopes, Coxeter groups, representation theory, partially ordered sets, lattices, and matroids, often motivated by problems arising from magic, games, and recreational mathematics.

In parallel to my academic work, I am a professional magician and a member of AMACA (Asociación de magos de Cali), a magicians' association federated by FLASOMA. My work aims to bridge rigorous mathematics, artistic performance, and scientific communication, always striving to make mathematics produce a genuine experience of magic and wonder. (I try xd)
