Postdoctoral Position, Mapping Big Data Systems

Applications are invited for a Postdoctoral fellowship at the University of Barcelona to work with Prof. M. Ángeles Serrano and Prof. Marián Boguñá at the Department of Condensed Matter Physics and UB Institute of Complex Systems (UBICS). The position is funded by a "Fundación BBVA" grant.

This is a postdoctoral position with a salary of €29,700 per year (before taxes) for one year renewable until june 2020. There will be additional support for conference travels.

The topic:

The discovery and understanding of the hidden geometry of complex networks have become fundamental problems within Network Science giving place to the field of Network Geometry. The research will focus on mixing of machine learning and statistical techniques for an efficient embedding of very large networks in hidden metric spaces to produce meaningful maps. We will create an online platform to host an atlas of network maps, and where scientists and interested people can produce theirs.

Essential Skills:

- A PhD in Physics, Computer Science, Computer/Electronic Engineering, or other relevant discipline is expected.
- Expertise in complex networks
- Excellent software development skills
- Excellent communication skills, verbal and written (English)

Informal queries about this position should be sent to

Application process:

Interested applicants are requested to submit

- a Curriculum Vitae including relevant publications and the name and contact details of 2 referees

- a one page cover letter explaining your interest in this specific position

Submissions should be sent by email with subject “MBDS Application” to

Interviews will be carried out as soon as suitable candidates are identified.

To successful candidate is expected to start in September  2018, or before (if possible).

World Trade Atlas 1870-2013

M. BoguƱƔ applications 01/03/2017

We present the World Trade Atlas 1870-2013, a collection of annual world trade maps in which distances incorporate the different dimensions that affect international trade, beyond mere geography. The atlas provides us with information regarding the long-term evolution of the international trade system and demonstrates that, in terms of trade, the world is not flat, but hyperbolic. You can check the evolution of world trade in this interactive video tool

New paper in Nature Communications

Nature Physics Research Highlights, A. Klopper publications 01/03/2017

The old maxim that it's less about what you know than who you know is an appropriate analogy for how the behaviour of a complex network can be profoundly influenced by the weights of its links. Read more

New paper in Nature Physics

M BoguƱƔ publications 01/02/2017

We show that multiplex systems are not random combinations of single network layers. Instead, they are organized in specific ways dictated by hidden geometric correlations between the layers.

Complex architecture of primes and natural numbers

NewScientist publications 08/10/2014

Is there a pattern behind prime numbers? This is one of the biggest questions in mathematics. Now networks that reproduce relationships between primes and non-primes could point the way to an answer. Read the paper.

New paper in Physical Review X

Phys. Rev. X publications 29/09/2014

Online social networks offer a data-driven way to study patterns of human behavior on small and large scales. Researchers have shown that individuals are significantly more likely to enroll in social networks based on the influence of one active friend than the influence of mass-media campaigns.
