On Sept. 26, 2-4 pm, we will host the first seminar of the Séminaires Parisiens en Réseaux (SPRES), with one talk from André Zanella, Ph.D. candidate with Marco Fiore at IMDEA Networks, Spain, followed by short presentations from seven among our master interns: Ali Awarkeh, Augustin Clero, David Kule, Farnaz Ebrahimishad, Hussein Khalil, Zifeng Zhang, Zisen Xu.

Title: Impact of Later-Stages COVID-19 Response Measures on 
Spatiotemporal Mobile Service Usage.

Speaker: André Zanella, IMDEA Networks, Spain

Abstract: The COVID-19 pandemic has affected our lives and how we use 
network infrastructures in an unprecedented way. While early studies 
have started shedding light on the link between COVID-19 containment 
measures and mobile network traffic, we presently lack a clear 
understanding of the implications of the virus outbreak, and of our 
reaction to it, on the usage of mobile apps. We contribute to closing 
this gap, by investigating how the spatiotemporal usage of mobile 
services has evolved through different response measures enacted in 
France during a continued seven-month period in 2020 and 2021.

Our work complements previous studies in several ways: it delves into 
individual service dynamics, whereas previous studies have not gone 
beyond broad service categories; it encompasses different types of 
containment strategies, allowing to observe their diverse effects on 
mobile traffic; it covers both spatial and temporal behaviors, providing 
a comprehensive view on the phenomenon. These elements of novelty let us 
lay new insights on how the demands for hundreds of different mobile 
services are reacting to the new environment set forth by the pandemics.

Bio: André Zanella is a PhD researcher at IMDEA Networks Institute. He 
received his bachelor’s and master’s degrees in Telecommunications 
Engineering at the Federal University of Parana, in Brazil, where he 
previously worked on data modeling of microelectronic RF systems. He’s 
currently a part of the Networks Data Science group, under Dr. Marco 
Fiore, working on mobile traffic analysis and remote sensing with 
network metadata, where his interests lay in developing techniques that 
help solving social sciences
problems using information gathered by 
network operators.
