Rosario N. MantegnaRosario N. Mantegna was a professor at CEU in a joint appointment of the Department of Economics and the Department of Network and Data Science (then Center for Network Science). Besides Palermo University, where he holds a professorship, he worked at the MPI for Quantum Optics in Munich, and at Boston University. His research concerns interdisciplinary applications of statistical physics. He started to work in the area of the analysis and modeling of social and economic systems with tools and concepts of statistical physics as early as 1990 and he is one of the pioneers in the field of econophysics. He coauthored the first book on econophysics. Rosario participated in and/or coordinated several projects, including Marie Curie Host Fellowship, COST, EU STREP, INET and national ones. He received his PhD in physics from Palermo University in 1990. |

Rossano SchifanellaRossano is an Assistant Professor in Computer Science at the University of Turin, Italy, where he is a member of the Applied Research on Computational Complex Systems group. He is a visiting scientist at Nokia Bell Labs and a former visiting scientist at Yahoo Labs and at the Center for Complex Networks and Systems Research at the Indiana University where he was applying computational methods to model the behavior of (groups of) individuals and their interactions on social media platforms. His research embraces the creative energy of a range of disciplines across data mining, network analysis, urban informatics, computational social science, and data visualization.

Giulia CencettiGiulia Cencetti earned her PhD degree at the University of Florence. Her interdisciplinary background (one year studying biology, then Bachelor’s and Master’s Degree in Physics and now a PhD in Information Engineering) took her to work on complex systems and in particular on the fascinating branch of dynamical systems on complex networks. She developed different models to explore the impact of network topology on the dynamical behavior of a system, having as an ultimate goal to apply a strategic external control. Applications are in biology, ecosystems stability, urban traffic, and information flow. |

Silvia FierascuSilvia was involved in the Ceunet/Indra project. She was also the founder of Data Stories at CEU. Her interdisciplinary empirical research explores the formation, evolution and effects of state capture and institutionalized grand corruption. She develops a novel theoretical and analytical framework, with applications to public procurement across countries and procurement markets, over time.

Reza JafariReza Jafari is a faculty member of physics complex systems at the Shahid Beheshti University. He started his collaboration with DNDS in the winter of 2016. His research interests are collective behavior and crises in financial and social science, complex networks dynamics, fractional calculus and its application in networks when memory influences the dynamics. Recently he has used fractional calculus to introduce aged networks. Indeed, age is the same as other properties of links such as weight and direction, and it can be considered a new property for a link. Evolution of social networks happens simultaneously with the variation of their links/nodes. However, sometimes it is not easy for some links/nodes to evolve in such a process because of their age. In real networks, some links/nodes can exist that are not happy with any variations. Understanding stability, aged phase transition, information transformation of social networks are some of the challenges of this project. Some other recent projects can be found on his page in ResearchGate (https://www.researchgate.net/profile/G_Jafari). |

Thomas LoufThomas is a PhD student in the IFISC laboratory in Spain and is spending a visiting period at CEU in the research team of Prof. Márton Karsai, contributing to the CIVICA EmoMap project. His task is to complete an extensive data analysis on a Twitter data corpus collected during the COVID-19 pandemic in Italy. The goal of the analysis is to create a network representation of the data to better understand how groups expressed similar emotions during the emergency and the following intervention periods. |

Sebastian Morel-BalbiAt the time of visiting, Sebastian was a PhD student at the University of Bath (UK). He holds a BSc in Physics and an MSc in Theoretical Physics both from the Sapienza University of Rome, where he specialised in statistical mechanics of disordered systems. His interest in the interdisciplinary applications of statistical mechanics led him to work in the area of complex networks. In particular, his thesis focuses on identifying the possible underlying mechanisms responsible for shaping the large-scale structure of complex networks. Amongst others, his research interests include strongly disordered systems, statistical inference, and optimisation problems. |

Carl NordlundCarl Nordlund was a Postdoctoral Research Fellow with a joint position at the Department of Network and Data Science (then Center for Network Science) and the Department of Political Science. He received his PhD in human ecology from the Department of Social and Economic Geography, Lund university, in september 2010, with undergraduate studies in human ecology, economic history, development studies, economics, political ecology, environmental justice, programming, mathematics, physics, and indonesian. In his thesis monograph, network-analytical methods were applied to international trade flows of agricultural and fuel commodities, examining would-be relations between structural positionality in trade networks and occurrences of ecological unequal exchange. Outside academia, he has worked for the Swedish EPA, WWF Sweden, TV4, KTH, Swedish Space Corporation etc. His research interest is in social network analysis - methods, applications and research design – focusing on political networks and international relations. Carl was involved in the Global Production Networks, Structural Inequalities and Unequal Exchange and the Ceunet/Indra projects.
