Article in El País (in Spanish) about how algorithms are now the big asset of companies, agencies and researchers to transform data into value
La era del algoritmo ha llegado y tus datos son un tesoro
“La primera revolución llegó hace unos años con el almacenamiento de inmensas cantidades de datos procedentes de las huellas electrónicas que todos dejamos. La segunda, en la que estamos inmersos, procede de la capacidad que tanto empresarios como usuarios o investigadores tienen para analizar estos datos.
Article (in Spanish) in MIT Technology Review (and the Sacyr innovation blog) about how automation is going to impact differently big or small cities.
Soluciones para ciudades grandes y pequeñas ante la automatización de empleos
La razón principal para que la automatización ataque más a los núcleos pequeños se debe a la propia naturaleza de los empleos disponibles en cada tipo de urbe. Las ciudades más pequeñas tienen más profesiones rutinarias y repetitivas, “como las tareas de servicios, labores mecánicas, fábricas y agricultura, que son susceptibles de ser automatizadas”, apunta el investigador del Media Lab y profesor de la Universidad Carlos III de Madrid Esteban Moro.
What are the properties of a long-lasting relationship? This important question as intrigued the social scientists during the last decades and has triggered numerous publications, surveys and experiments to detect what patterns are behind social relationships that persist. Probably the most famous finding is that of Granovetter who proposed that strong relationships are the ones more likely to persist in the future. And what is a strong relationship? According to Granovetter, a strong relationship is that with high intensity (a lot of interactions), intimacy (mutual confiding) and large structural redundancy (lots of common friends).
This episode of the Spanish television program El Cazador de cerebros show the uses of Big Data in social problems. Shot at MIT Medialab, I share the episode with friends like Manuel García Herranz (who works and shows much cooler things that I do.)

Abstract: Social networks are made out of strong and weak ties having very different structural and dynamical properties. But what features of human interaction build a strong tie? Here we approach this question from a practical way by finding what are the properties of social interactions that make ties more persistent and thus stronger to maintain social interactions in the future.
One of my favorite activities is to teach my field or research (network science) to high-schoolers. We (together with my colleague Cristina Brändle) have been doing that from our university to the local high schools in Madrid. Since they know concepts like equations, probability or geometry, it is somehow easy to show them concepts like what is a network, small world, friendship paradox or centrality. We usually have transparencies and allow them to work on Excel to perform some calculations which works well to understand the basic concepts of networks.

Abstract: Human behavior shows strong daily, weekly, and monthly patterns. In this work, we demonstrate online behavioral changes that occur on a much smaller time scale: minutes, rather than days or weeks. Specifically, we study how people distribute their effort over different tasks during periods of activity on the Twitter social platform. We demonstrate that later in a session on Twitter, people prefer to per- form simpler tasks, such as replying and retweeting others’ posts, rather than composing original messages, and they also tend to post shorter messages.
Nice article (in Spanish) in Yorokobu magazine about the use of Twitter in science, highlighting our work on the use of social media for rapid assessment of natural disaster management
El romance entre Twitter y la ciencia
«Twitter y las otras redes sociales están entre los más grandes archivos de actividad humana existentes y, al contrario que con las encuestas, ahora tenemos la posibilidad de analizar millones de mensajes, opiniones e interacciones de personas en diferentes contextos como la política, economía o el ocio», explica el matemático Esteban Moro, investigador en la Carlos III de Madrid.
Some pictures of different activities during this year 2016
I was invited to give a tutorial about temporal networs at the Workshop on Complex Network Mining and Analysis in Workclaw. Here we are hanging out with some of the other speakers (Bruno Goncalves and Marton Karsai)
Just arrived to Boston, I gave a talk at Netsi about our work on Temporal Networks at Netsci, Northeastern University.
Working at the Medialab I got the opportunity to talk about our work in other groups, like Scalable Cooperation here.
