Yairon Cid Ruiz

On 26/06/2019, I defended my PhD thesis at the Departament de Matemàtiques i Informàtica of the Universitat de Barcelona. I am part of the ARCADES network. My advisor was Carlos D'Andrea.

In September 2019, I will start as a postdoctoral researcher at the Max Planck Institute for Mathematics in the Sciences in the group led by Bernd Sturmfels.

Here is my Curriculum Vitae.

Here is a copy of my PhD thesis.

Research

My main research interest is commutative algebra and its interactions with algebraic geometry and combinatorics. I like topics related to blow-up algebras, local cohomology, syzygies, regularity and edge ideals. I am particularly interested in the relations between blow-up algebras and certain criteria for the birationality of rational maps.
