Javier Borge-Holthoefer completed his PhD in the Department of Computer Science and Mathematics of the University Rovira i Virgili, at Tarragona, under the supervision of Dr. Alex Arenas. His PhD was devoted to Cognitive Dynamics, which places cognitive phenomena (specially language-related) in the framework of complex networks theory. Since then he has worked as a Post-Doctoral Researcher at University of Zaragoza, Department of Condensed Matter, developing his research at the Institute for Biocomputation and Physics of Complex Systems (BIFI). While he persists in the study of cognitive phenomena from a statistical physics point of view, he also develops research on social networks (collective action, on-line communication platforms), and other topics occasionally.

Dr. Sandro Meloni was born in Rome (Italy) on October  2nd, 1982. He carried out his undergraduate studies at the Department of Informatics and Automation of the university of Rome “Roma Tre”. He got his master degree in computer science on December 21st 2006 with the mark of 110/110 cum laude. In October 2007 he started his Ph.D. at the same university under the tutoring of Prof. Stefano Panzieri and Dr. Yamir Moreno dealing with Epidemic and Traffic Dynamics on large technological networks. Actually, he is a first year post-doctoral fellow at the Institute for Biocomputation and Physics of Complex Systems (BIFI) of the University of Zaragoza in Spain. He is interested in non-linear and collective dynamics on Networks. He also has been visiting scientist at the Institute for Scientific Interchange (ISI) in Turin and the Department of Physics of the University of Catania (Italy).
