A selection of work on media ecosystems, information flows, and public-interest data. Most of these projects are developed within the Media Ecosystem Observatory and the Canadian Digital Media Research Network.

Building a Media Ecosystem Observatory from Scratch

National-scale digital trace infrastructure for monitoring Canadian political and media discourse across platforms in near real time.

  • Role: Digital research lead and co-author of the core infrastructure paper.
  • What it does: Custom crawlers, unified schemas, semantic embeddings and dashboards that track news, political actors, influencers and key events across multiple platforms.
  • Why it matters: Provides shared infrastructure for researchers and partners to study modern information environments, including elections and major policy interventions.

Power Shift: Political Influencers in Canada’s Online Ecosystem

Mapping the rise of political influencers and their role in shaping Canadians’ exposure to political content across major platforms.

  • Scope: Multi-platform dataset covering millions of posts from January 2024 to July 2025, spanning influencers, politicians, news outlets and other actors.
  • Key finding: Political influencers now reach more people than news outlets or politicians on several major platforms, shifting who has the “loudest voice” during elections.
  • Public impact: Results featured in national media coverage and used to contextualize changes in Canada’s information landscape.

Earlier work: digital heritage, crisis informatics & web archives

Before focusing on contemporary media ecosystems, I worked on digital heritage, web archiving and the construction of online memory around major historical and traumatic events.

Constructing the Online Memory of the First World War (BnF & Télécom ParisTech)

Postdoctoral work within the Labex project between the Bibliothèque nationale de France (BnF) and Télécom ParisTech, studying how the First World War is remembered and reconstructed online.

  • Focus: Mapping the French web dedicated to the Great War and analysing how digitized archives, forums and amateur communities contribute to the construction of historical memory.
  • Methods: Large-scale web data, hyperlink network analysis, text mining and qualitative inquiry on sites, forums and digital libraries (e.g. Gallica and partner platforms).
  • Impact: Helped document how “ordinary” users and heritage institutions jointly shape digital memory, and informed BnF’s thinking on online heritage uses and interfaces.

Digital Memory of Crises: Paris & Nice Attacks (INA, CNRS)

Work with the Institut National de l’Audiovisuel (INA) and CNRS researchers on how major traumatic events — including the Paris attacks (2015) and the Nice attack (2016) — were archived, remembered and reconstructed online.

  • Focus: Large-scale analysis of web archives, broadcast media and social media traces collected during and after the attacks.
  • Methods: Web crawling, hyperlink network analysis, temporal activity modeling, text mining and cross-platform media comparison.
  • Impact: Supported CNRS research programs on collective memory, crisis informatics, terrorism studies and digital heritage, and informed INA’s archiving strategies for national traumatic events.
