2013 – Barcelona

With the definitive explosion of information technologies, complex networks are everywhere: from the internet to the metabolic system, going through transport infrastructures and social systems.

We have plenty of data to play around, but do we understand the theory on how to apply it properly? What aspects remain to be solved? Are the existing models useful and relevant? Those inspiring questions have arized in the field of complex science since its birth in the 90’s.

Coinciding with the European Conference on Complex Systems (ECCS’13) in Barcelona and profiting the opportunity offered by the presence of a wide variety of experts in different topics in Barcelona, we have decided to organize a Warm-up school to prepare such a big event. The projected school aims to offer young researchers the opportunity to learn new methods, present their work and meet fellow researchers.

Without knowing it, this was the first Warm-up of a long series!


Warm-up: September 13-15, 2013, the weekend just before ECCS’13.


Thanks to the generosity of the city council, we are able to offer a unique location for the school: The Barcelona Art Factory “Fabra i Coats”.

We wanted to give a dynamical flavor to the courses and so we decided to locate the event not in a regular class but in this old factory build on the late XIX century and recently restored, a living part of the industrial historical heritage of Barcelona.


Being the south of Europe a very active and known area in the field of complexity, three renowned researchers from Barcelona (UPC) and Tarragona (URV) will each present a different aspect of complex networks in three hour sessions. Names such as Prof. Romualdo Pastor-Satorras, Prof. Marta Sales-Pardo and Prof. Àlex Arenas should sound familiar to any interested student. Furthermore, we plan a meeting where each participant will have the possibility to share with the others his work, organized as a flash presentation workshop.  The coach of the planned sessions will be Dr. Jesús Gómez Gardeñes (scientific chair of the school) and other invited scientists present at the ECCS13’. Of course, a major social event is included, to stimulate networking and “prepare” the official ECCS conference.

Social Event

ECCS warmup finale: Complex BBQ

We are young, we like science and we like meeting new people.

That is why we love social events! We plan on organizing a major social event at the end of the school to encourage networking among participants and stimulating science discussion. After all the hard work, we will need some time to party and “prepare” the official congress!

On Sunday, we invite all the participants to join us in the final BBQ to close the Warm Up and start the official ECCS congress week. The party will consist in a BBQ organized in Vilanova i la geltrú, a cosy town in the mediterranean coast 30 minutes away from Barcelona. A nice catalan Villa is waiting for us there. Will you miss it?

YRNCS Satellite

This is a Satellite designed for Young Researchers, by Young Researchers. We give the opportunity to PhD students and to PostDocs to present their work to other young researchers participating in the Satellite.

What is YRNCS Satellite @ ECCS’13?

YRNCS Satellite @ ECCS’13 is a Satellite organized by the Young Researchers Network on Complex Systems (YRNCS) and its aim is to bring together the community of young researchers who work on Complex Systems. With this initiative we want to promote the creation of a big community of young researchers and scientists who will exchange ideas and consult each other, who can work together and build the basis of future collaborations.

Program – First part – September 15th

  • 17:00-18:10 – Panel Session: “Complexity tales: a guide for the young researcher”
  • 18:20-19:20 – Speed Presentations Session: 5 minutes talks by young researchers
  • 20:00-21:00 – Live Demonstrations Session

Dinner will follow!

Program – Second part – September 19th

  • Poster session: During lunch and coffee breaks.
  • 15:00-16:00 – Panel Session: “Complexity tales: a guide for the young researcher”
  • 16:10-17:00 – Speed Presentations Session: 5 minutes talks by young researchers
  • 17:10-18:00 – Discussion – Future plans

On September 19th the YRN on Complex Systems will be joining another Satellite, the: “Global Computing for our Complex Hyper-connected World”. This will take place at 18:30. We will attend their panel session and be offered a time slot to make questions to the panel participants.

Panel Series – “Complexity tales: a guide for the young researcher”

  • How is it like to be a young researcher working on Complex Systems?
  • What are the possibilities opening ahead?
  • How would a young researcher make the choice on which field of Complex Systems to work on?
  • What are the decisions he/she has to take?
  • Is there a safe – easy route?
  • How can he/she become a successful researcher?
  • What is the advice senior researchers and professors would give to young researchers?
  • What are the main topics scientists on complex systems work on?
  • How are different scientific fields united to serve the science of complex systems?

These are a few of the many topics that are going to be discussed during the panel sessions. Professors and researchers Prof. J. Johnson, Dr. D. Chavalarias, Dr. A. Barrat, Prof. C. Gershenson, Prof. Y. Moreno and Prof. A. Vespignani are going to participate in the event and help the young researchers understand not only what they work on but also how they reached the current stage of their career, what is the advice a young researcher should follow to step towards success. Of course at the end, the young researchers attending the panel will have the time to ask their own questions to the panel participants and even talk with them in person during the reception that will follow.
