Rodrigo San-José

I am currently a postdoctoral researcher at the University of Valladolid, Spain. My main research interest is algebraic coding theory. In particular, I am focused on studying applications in quantum error-correction and cryptography. I am also interested in the applications of commutative algebra to coding theory.
Here are some quotes that I like:

• Related to work: [1], [2] (other version [3]).
• Literature: [1], [2], [3], [4], [5], [6], [7], [8].
• Miscellaneous: [1], [2], [3], [4].

My full name is Rodrigo San José Rubio.
