Noé Gaumont

Computer science researcher working on Politoscope. I study the structure of networks such as the Twitter network for the Politoscope project. The main objective is to detect communities of political activists on Twitter but also, and above all, to track their evolution through time. This allows citizens and journalists to better understand the political organization existing on Twitter. To this end, I use and create graph analysis tools.

Key words: Graph, Community Detection, Temporal Network.

François LAVALLÉE

Currently interning with the PERSIST team, my research project is part of the theory of viability. I work on modeling strategies to manage plant invasions. My research focuses on the Japanese Knotweed, a specie present along roadsides and that may endanger the safety of road users. The purpose of this internship is to put forward two levels of modeling: (i) a stochastic level upon arrival of new individuals or species and (ii) a deterministic level for modeling the species population when their number is significant.
