High-Resolution Social Networks: Measurement, Modeling and Applications
6 giugno 2019 alle 14:30
Sala Consiglio 8 Piano, via Celoria 18
Speaker: Ciro Cattuto, ISI Foundation
Persona di riferimento: Nicolò Cesa-Bianchi
Digital technologies provide the opportunity to quantify several important human behaviors and have revolutionized the way we think about human mobility and social networks, enabling new research in computational social science, urban mobility, epidemiology and public health. In this talk I will review the experience of the SocioPatterns project (www.sociopatterns.org), an ongoing, decade-long international collaboration on studying high-resolution social networks using wearable proximity sensors. I will discuss technology requirements and measurement experiences in relevant environments such as schools, hospitals and households. I will illustrate the complex features found in time-resolved social network data, and discuss data representations and data incompleteness. I will show how methods from network science and machine learning can be used to detect structures and to understand the role that specific nodes or structures play for dynamical processes occurring over the network, such as epidemic spreading. I will close with an overview of applications and future challenges.
Dr. Ciro Cattuto is the Scientific Director of ISI Foundation (Torino, Italy and New York, NY, USA). His research interests include data science, network science, computational social science and public health. He is a founder and principal investigator of the SocioPatterns collaboration, an international effort on studying human and animal social networks with wearable sensors, with applications to public health and computational social science. Dr. Cattuto holds a PhD in Physics from the University of Perugia, Italy and has carried out interdisciplinary research at the University of Michigan (Ann Arbor, USA), at the Enrico Fermi Center and Sapienza University (Rome), and at the Frontier Research System of the RIKEN Institute (Japan). He is an adjunct professor at the University of Torino and at Sapienza University, and a Scientific Board member of the PhD in Data Science of Sapienza University. He is an editorial board member of EPJ Data Science, Nature Scientific Data, Journal of Computational Social Science, PeerJ Computer Science and Data & Policy, and he has been an organizer and chair of leading conferences in computer science, complex systems and network science.
