The project is part of the Vidi project “The economy of digital influence operations”, led by Associate Professor Jon Roozenbeek, and focuses on the market infrastructure behind disinformation and influence operations in digital environments.
The PhD research will examine the online manipulation economy, including fake accounts, engagement services, and bot armies sold online. The successful candidate will map buyers and sellers in this marketplace, conduct interviews with key actors, and build bespoke analysis pipelines using social media data and financial data to study downstream consequences.

Strong quantitative research skills are required, including advanced statistical analysis and time series analysis. Experience with Python and R is essential, and excellent academic writing in English is expected. Knowledge of Russian and/or Mandarin is considered an advantage. The department also values independence, collaboration, and clear communication.
The position is four years and fully funded, with a salary starting at €3,204 gross per month and rising to €4,051 gross per month in the fourth year.
