Research:

I belong to the Software Department and to the Nanoengineering Research Center, both at the Technical University of Catalonia (UPC). My current areas of interest are:

• Multiagent Systems (from the complex systems viewpoint)
• Pedestrian Dynamics (see also here, here or here)
• Astronomy: I'm member of the Grup d'Estudis Astronomics (G.E.A.) and also of ASTER (Barcelona Astronomical Association) since 1985 (unfortunately, I'm not a very active member)
