Ferdinand is a PhD student in Computer Science and Sociology. His researched focuses on the dynamics of online community and in a broader sense of social phenomena that can be represented with a temporal network structure. He attempts to leverage the tools of machine learning like Graph Neural Networks or Large Language Models and design them for social science studies. Ferdinand’s three-months visit at the CSS team of Center Marc Bloch aims at producing a thought process and algorithms on the temporal dynamics of online phenomena. It includes the study of the temporality of topics in online debates and the dynamic detection of online communities.
