Graph theory provides a language for studying the structure of relations, and it is often used
to study interactions over time too. However, it poorly captures the intrinsically temporal and …

Dynamic graph drawing algorithms take as input a series of timeslices that standard, force-
directed algorithms can exploit to compute a layout. However, often dynamic graphs are …

Link streams offer a good model for representing interactions over time. They consist of links
$(b, e, u, v) $, where $ u $ and $ v $ are vertices interacting during the whole time interval …

Infections can spread among livestock notably because infected animals can be brought to
uncontaminated holdings, therefore exposing a new group of susceptible animals to the …

Studying IP traffic is crucial for many applications. We focus here on the detection of
(structurally and temporally) dense sequences of interactions that may indicate botnets or …

Vehicular cooperation taking place in Intelligent Transportation Systems (ITS) aims to solve
traffic issues or to improve road safety for vehicles and vulnerable road users. Such …

Gab is an online social network often associated with the alt-right political movement and
users barred from other networks. It presents an interesting opportunity for research because …

Résumé The journey recounted in this document spanned a period of about 10 years, from
the end of the PhD (2007) to current (early 2018). The rst ve years correspond to two …

For a long time, researchers have worked on defining different metrics able to characterize
the importance of nodes in static networks. Recently, researchers have introduced …

This document is the first part of the author's habilitation thesis (HDR), defended on June 4,
2018 at the University of Bordeaux. Given the nature of this document, the contributions that …
