Epidemics on Networks
Speaker: Piet Van Mieghem, Delft University of Technology, The Netherlands
Abstract: The talk is divided into two parts. First, I will briefly summarize the essential theory of epidemics on fixed contact graphs. In the second part, I will talk about aspects of the theory, that in my opinion, may deserve more attention in the future. Most models of epidemics implicitly assume a Markovian way of thinking and omit the difficult dependence on the past. Although little is known about more realistic modeling, we will sketch (a) some non-Markovian aspects and (b) illustrate that the prevalence, i.e. the average fractions of infected nodes, in time-varying networks can mimic the reported COIVD-19 prevalence over long time intervals.
Bio: Piet Van Mieghem is a professor at the Delft University of Technology with a chair in telecommunication networks and chairman of the section Network Architectures and Services (NAS) since 1998.
His main research interests lie in the modeling and analysis of complex networks (such as infrastructural, biological, brain, and social networks) and in new Internet-like architectures and algorithms for future communications networks. The focus of his chair is broadened from telecommunication networks to Network Science.
He is the author of four books: Performance Analysis of Communications Networks and Systems, Data Communications Networking, Graph Spectra for Complex Networks, and Performance Analysis of Complex Networks and Systems.
He is a board member of the Netherlands Platform of Complex Systems, a steering committee member of the Dutch Network Science Society, an external faculty member at the Institute for Advanced Study (IAS) of the University of Amsterdam, and an IEEE Fellow. He was awarded an Advanced ERC grant in 2020 for ViSiON, Virus Spread in Networks.
Professor Van Mieghem received a Master's degree (Magna cum Laude) and a Ph.D. degree (Summa cum Laude with Congratulations) in Electrical Engineering from the K.U.Leuven (Belgium) in 1987 and 1991, respectively. Before joining Delft, he worked at the Interuniversity Micro Electronic Center (IMEC) from 1987 to 1991. From 1993 to 1998, he was a member of the Alcatel Corporate Research Center in Antwerp where he was engaged in performance analysis of ATM systems and in network architectural concepts of both ATM networks (PNNI) and the Internet. He was a visiting scientist at MIT (Department of Electrical Engineering, 1992-1993) and a visiting professor at UCLA (Department of Electrical Engineering, 2005), at Cornell University (Center of Applied Mathematics, 2009), at Stanford University (Department of Electrical Engineering, 2015) and Princeton University (Department of Electrical and Computer Engineering, 2022).
Currently, he serves on the editorial board of the OUP Journal of Complex Networks. He was a member of the editorial board of Computer Networks (2005-2006), the IEEE/ACM Transactions on Networking (2008-2012), the Journal of Discrete Mathematics (2012-2014), and Computer Communications (2012-2015).
