Also a common nickname for Ignacio in Spain is "Nacho".

My main area of expertise is cryptography, where I work in the topic of secure multiparty computation and its building blocks such as secret sharing schemes, commitment schemes, oblivious transfer protocols, etc.

I am especially interested in the interplay between these topics and both the theory of error-correcting codes and abstract algebra: finite fields, algebraic number theory, algebraic geometry...

Member of the project SECURE , funded by Aalborg University under its Call for Interdisciplinary Research Projects, where I was leader for the Workpackage ``Secure Computation'' between 2018-2019.

I was an organizer of Breaking Borders in Research III , a conference organized by the Spanish Scientists in Denmark (CED/SFD), March 2019.

I was a scientific organizer of a two-week Workshop on Information Theoretic Cryptography at the Lorentz Center (Leiden University) in May 2013.

Student PBL projects:

Following the PBL (problem based learning) principle, much of the teaching in Aalborg University takes place through group projects. I have supervised projects in the following topics:

- Cryptography (RSA, homomorphic encryption, ecret sharing, multiparty computation).
- Coding theory (List decoding).
- Algebraic function fields and codes.
- Gröbner Basis.
- Ordinary Differential Equations.

- Spring 2019: Cybersecurity, PhD. course, program of Electric and Electronic Engineering.
- Spring 2019: Datalogiens Matematiske Grundlag (Mathematical Foundations of Computer Science), common bachelor course for the educations: Informatics, Information Technologies and Interaction Design.
- Fall 2018: Computer Algebra, bachelor course in Mathematics at Aalborg University.
- Fall 2018: Information and coding theory, master course in Mathematical Engineering (MATTEK).
- Spring 2018: Coding theory, bachelor course in Mathematics at Aalborg University.
- Fall 2017: Computer Algebra, bachelor course at Aalborg University.
- Fall 2015: Coding Theory, master course in Computer Science, Aarhus University.
- Fall 2012: Cryptology, Dutch national master program Mastermath.

I was vice-delegate in Aalborg of the association of Spanish Scientists in Denmark (CED-SFD).

I was in the board of the PhD and postdoc House Activity group of Aarhus University in the summer-fall of 2015. If you are a PhD. student or postdoc at AU, I encourage to join some of the events organized by the group.

In 2012, I played a small stunt in a short movie titled the Cat (although you won't see my face) directed by my friend Giannicola Scarpa. The movie competed in the Quantum Shorts Film Competition organized by CQT, National University of Singapore. Although it didn't win a prize, it ended second in the Popular Choice award .

Participation in Mathematical Olympiads. I ended up 5th in the Spanish Mathematical Olympiad, and participated in the International Mathematical Olympiad in 2001 (Washington, USA).

I used to play chess at a strong club player level. I had a 2100+ FIDE Elo Rating when I ''retired''.
