Title:
Polarization, Misinformation, and Hate: Investigating Social Dynamics with Online Data
Abstract:
The COVID-19 pandemic has highlighted the challenge of conveying and communicating complexity and uncertainty to the public, also given the increasing central role of the Internet and social media. Designed to maximise users' presence on the platform and to deliver targeted advertising, social media transformed the information landscape and have rapidly become the main information sources for many of their users. Information spreads faster and farther online, in a flow-through system where users have immediate access to unlimited content. This may facilitate the proliferation of mis- and dis-information, generating chaos, and limiting access to correct information. In this talk, I will provide an overview of how social dynamics and behavioural patterns can be investigated and analysed with online data, and discuss how data-driven insights can be used to design effective strategies to counter misinformation and improve the overall quality of the information system.
Speaker Bio:
Fabiana Zollo is an Assistant Professor in the Dept. of Environmental Sciences, Informatics and Statistics and Research Fellow in the Center for the Humanities & Social Change at Ca’ Foscari University of Venice. Her research investigates information and misinformation spreading, social dynamics, and the emergence of collective narratives on online social media. She collected several papers on this topic, with both national and International co-authors. Since 2019, she is serving as an External Expert to the European Food Safety Authority (EFSA). She is a member of the Task Force “Data Science” established by AGCOM, the Italian Communications Regulatory Authority, and a member of the Working Group established by the Italian Presidency of Council to study the phenomenon of disinformation on COVID-19.

WED@NICO SEMINAR: Rosemary Braun, Northwestern University "The Scale of Life"
Northwestern Institute on Complex Systems (NICO)

Speaker:
Rosemary Braun, Associate Professor, Department of Molecular Biosciences, Northwestern University
Title:
The Scale of Life
Abstract:
Living systems exhibit surprising and beautiful self-organization at all scales. At the atomic level, proteins self-assemble into macromolecular complexes. The function of these machines is orchestrated within the cell by regulatory networks, whose activity is in turn dictated by, and coordinated with, the cells environment. This coordination takes place across large spans of space and time: the size and lifetime of organisms as large as the blue whale. Populations and ecosystems of many organisms in turn exhibit remarkable emergent dynamics. Today, advances in single-cell assays enable us to probe the molecular state of every cell in a sample in high-dimensional detail. But is this the correct scale at which to probe living systems? What can we learn from this data, and how can we abstract from the microscopic details to macroscopic phenotypes? In this talk, I will discuss some of our recent work bridging the cell and tissue/organism scales, and discuss some challenges and opportunities for the future.
Speaker Bio:
Rosemary Braun is an Associate Professor of Molecular Biosciences, Applied Mathematics [ESAM], and Physics at Northwestern University. A theoretical physicist by training, she earned her PhD in Physics from the University of Illinois, followed by a Masters in Biostatistics from Johns Hopkins University. She completed her postdoctoral training at the National Cancer Institute (NIH) before joining Northwestern as a faculty member. Today, she works at the intersection of statistics, mathematics, and biology to develop computational tools for analyzing high-dimensional data. In addition to her Northwestern affiliations, she is also Associate Director of the National Institute for Theory and Mathematics in Biology, as well as external faculty of the Santa Fe Institute.
