My current research is with the Graphs and Combinatorics Group of DMAT in the application of Graph Theory to the design of topologies and communication strategies for interconnection networks and include:

• The design of large networks, particularly the degree-diameter problem for vertex-symmetric networks.
• Communication problems: broadcasting and gossiping.
• The study of small-world scale-free networks, like the network associated to the Erdös number (mine is 2).
• Design and analysis of deterministic models for complex networks.
• The use of combinatorial optimization algorithms for problems like the design of certain classes of networks or communication strategies, planarization, the design of codes, coloring of graphs or frequency assignment:
• Simulated annealing, tabu search
• Genetic algorithms, genetic programming
• Multi-agent algorithms (ants), immune system based algorithms.

This page was created in June 10, 1994. In 1996, a project to keep "snapshots" of the WWW was started at web.archive.org , with computers at the new Alexandria Library and somewhere in California. Go to the past and connect to my homepage as it was on December 1, 1996.

We put the first geocache (geoamagatall) of the Iberian peninsula (February 18th, 2001). Listen to an interview (Radio Barcelona), March 2001, on this topic. Another short interview related with the 5th anniversary was broadcasted by Catalunya Informació (March 1, 2006). The newspaper AVUI wrote an article in August 11th, 2006.

Before having my post at DMAT and from 1982 to 1985 I was with the Autonomous Government, Generalitat de Catalunya, Directorate of the Universities. From 1978 to 1982 I was a lecturer at the Universitat Autonoma de Barcelona where I did my Ph.D. on exact solutions to the Einstein's field equations (more on this): Solucions Estacionàries i Axisimètriques a les Equacions d'Einstein.
