My research papers.
Some talks I have given.
I am (or have recently been) involved in the organization of the following workshops:
- International Fall Workshop on Geometry and Physics (Castro Urdiales, September 3-6 2008).
- Workshop on Geometric and Topological Combinatorics (Alcalá de Henares, 31 August-5 September, 2006). This is a satellite conference of ICM2006.
- XIII Encuentro de Topología (Santander, November 2006). A Spanish meeting on Topology.
- XI Encuentros de Geometría Computacional (Santander, 27-29 June, 2005). A Spanish meeting on Computational Geometry.
- Algebraic and Geometric Combinatorics (Crete, 20-26 August, 2005). This was part of a series of Euroconferences on Mathematics in Crete.
I work mostly with people in the groups Discrete and differential geometry and Computational Algebra and Geometry of my department.
I was in charge of the Erasmus/Socrates program in Mathematics in my university until May 2003.
I was visiting the Math Department of University of California Davis until March 2008. My web there was http://www.math.ucdavis.edu/~santos.
Some pages related to the MSRI Summer School on Triangulations of point sets, that I organized in July 2003 jointly with Jesús A. de Loera and Jörg Rambau.
Spanish version of Maths Thesaurus, an online multilingual Mathematics dictionary for primary and secondary school.
These were some useful (at least for me) links. But I have not updated this since long; most of the contents are probably obsolete...

Research areas:

Computational geometry (Delaunay triangulations, pseudo-triangulations)
Discrete and combinatorial geometry (oriented matroids, triangulations of convex polytopes)
Real algebraic geometry (topology of real algebraic plane curves, decomposition of polynomials in sums of squares)

These are my two youngest collaborators. Click on the pictures to see them as they deserve.
