Webinar 25/06/2020

Date: 25 June, 16h (CET, GMT+2, Barcelona/Madrid/Paris/Berlin)

Speaker: Santiago F. Elena, Institute for Integrative Systems Biology, CSIC​

Title: "Why some patients develop a severe syndrome while other remain asymptomatic? Early-warning signals associated with the phase transition from health to disease."

You can see the webinar here:


Abstract: One of the most outstanding observations during COVID-19 pandemics is that some patients have an asymptomatic infection while others suffer severe symptoms, some of them becoming fatal. Is there any relation between the global gene expression state of patients and they propensity to suffer an asymptomatic infection? Is it possible to identify which genes, or groups of them within a regulation network, may serve as markers to predict the clinical fate of a patient before the presence of any symptom? In this seminar I will introduce the fundamentals of the theory of Dynamical Biomarkers of Networks (DBN), illustrating their application to the analysis of transcriptomic data during disease progression in a pathosystem model.


Títol: "Perquè alguns pacients desenvolupen símptomes severs mentre uns altres són asimptomàtics? Biomarcadors d'una transició de fase associada a la progressió de la malaltia”

Resum: Una de les observacions més destacables fetes durant l'epidèmia de la COVID-19 és que alguns pacients passen la infecció de manera asimptomàtica mentre que uns altres pateixen símptomes severs que en un percentatge de casos tenen un desenllaç fatal.  Existeix alguna associació entre l'estat d'expressió gènica global dels pacients i la seua propensió a patir una infecció asimptomàtica?  És possible identificar quins gens, o grups d'ells en una xarxa de regulació, servirien de marcadors per a predir el destí clínic d'un pacient abans que mostre cap símptoma?  En aquesta xarrada presentaré els fonaments de la  teoria dels biomarcadors dinàmics de xarxes (DNB) i il·lustraré la seua aplicació a l'anàlisi de dades transcriptòmics presos al llarg de la progressió de la malaltia en un patosistema model.

Date: 18 June, 16h (CET, GMT+2, Barcelona/Madrid/Paris/Berlin)

Speaker: Nuria Oliver, Data-Pop Alliance & ELLIS

Title: "Data Science to fight against COVID-19"

You can see the webinar here:



In my talk, I will describe the work that we have done within the Commission on AI and COVID-19 for the President of the Valencian Region. As commissioner, I have led a multi-disciplinary team of 20+ scientists who have volunteered since March 2020. We have been working on 4 large areas: (1) human mobility modeling; (2) computational epidemiological models (both metapopulation and individual models); (3) predictive models; (4) citizen surveys (

I will describe the results that we have produced in each of these areas and will share the lessons learned in this very special initiative of collaboration between the civil society at large (through the survey), the scientific community (through the Expert Group) and a public administration (through the Commissioner at the Presidency level)

Barcelona Webinar 11/06/2020

Speaker: Manlio de Domenico, CoMuNe Lab, Fondazione Bruno Kessler

Title: "Tackling complexity: foundations and applications"


Complex systems consists of units whose interactions at a microscopic scale lead to the spontaneous emergence of collective behavior and other unexpected phenomena at the meso- and macroscale. In this seminar I will introduce some basic concepts and tools of complexity science without relying on technicalities.
In the second part of the seminar I will briefly discuss the relevance of big data for the analysis of complex systems and, more specifically, of socio-technical systems, spanning from the rise of collective attention to one of the most relevant phenomena observed during the COVID-19 pandemic: the infodemic related to coronavirus.

15:00-16:00 Seminari a càrrec de Dra. Roberta Sinatra (Assistant professor, ITU Copenhagen)

Title: Quantifying the biases of scientific success

Abstract: Performance, also referred to as quality of fitness, represents the objective achievements of an individual, like the winning record of an athlete or the body of work of a scientist. In contrast, success, also referred to as impact, popularity, or visibility, is a collective phenomenon, indicating a community’s reaction to an individual’s performance. Why is the difference between performance and success important? Because in many areas of human activity, we often rely on success to measure performance - especially in science, where citations and visibility are constantly used to gauge quality, to assign recognition, and to allocate resources. Yet, success is strongly susceptible to effects that have NOTHING to do with performance, like gender or reputation. In this talk, we study success and impact in science, and ask: What is the role of luck in achieving high impact? What is the effect of gender and reputation on success? Can we model the different career evolution of male and female scientists? Based on the premise that success is a collective phenomenon, we use the tools of network science, data science, and computational social science to provide quantitative answers to these questions. 

Bio: Roberta Sinatra is Assistant Professor at IT University of Copenhagen, and holds visiting positions at ISI (Turin, Italy) and Complexity Science Hub (Vienna, Austria). Her research is at the forefront of network science, data science and computational social science. Currently, she spends particular attention on the analysis and modeling of dynamics that lead to the collective phenomenon of success, with focus on science and art, and on data-for-good applications. Roberta completed her undergraduate and graduate studies in Physics at the University of Catania, Italy, and was first a postdoctoral fellow, then a research faculty at the Center for Complex Network Research of Northeastern University (Boston MA, USA). Her research has been published in general audience journals such as Nature and Science, and has been featured in The New York Times, Forbes, The Economist, The Guardian, The Washington Post, among other major media outlets.

Aula 1A, 2a pta, Facultat de Quimica, UB 14/11/2019

El 14 de Novembre de 2019 l'UBICS participarà a la Setmana de la Ciència seguint el següent programa: 

• "Xarxes complexes per a tothom"

10:30 a 11:00 Xerrada introductòria, a càrrec de Albert Diaz-Guilera (Director de l’Institut):

El nostre món esdevé cada dia més connectat a través de xarxes que permeten una comunicació instantània i la difusió d'informació. Al mateix temps, el grau en què la gent conegui aquestes xarxes jugarà un rol important a l'hora de determinar el benefici d'aquesta creixent connectivitat en la societat. En poques paraules, una societat connectada ha de conèixer com i perquè es dóna aquesta connectivitat: el coneixement bàsic de com les xarxes poden ser usades com una eina per descobrir i prendre decisions, conèixer els seus potencials beneficis i possibles punts febles, així com fer-lo més accessible als habitants d'aquest món cada cop més connectat. Us convidem a una sessió interactiva on veureu algunes característiques matemàtiques senzilles de les xarxes.

• " Simulacions de Sistemes Complexos"

11:00 a 11:30 Taller on es mostrarà de forma molt didàctica diverses simulacions que ens faran entendre millor el mon dels Sistemes Complexos. Pots trobar-ho aquí.

• " Visites a Laboratoris"

A continuació es visitaran els laboratoris dels investigadors en la ciència dels Sistemes Complexos.

11:30 a 12:00 Laboratori de neurofísica (Jordi Soriano-Fradera):

12:00 a 12:30 Laboratori de materials, transicions de fase i sistemes multiescala (Eduard Vives).
