About me

I am a Post-doctoral researcher at the médialab Sciences Po in Paris. I work on the AI-Political Machines project under the supervision of Pedro Ramaciotti Morales.

My research is devoted to the study of opinion dynamics in online social platforms, between theoretical models and empirical observations. I have a keen interest in the multi-dimensional aspect of opinions and its impact on polarisation. I find particularly important the signed aspect of social networks, incorporating both friendly and hostile relationships and interactions. I also study recommender systems, and policies related to the regulation of the online space from a practical perspective.

I am also affiliated with the Paris Institute of Complex Systems, and the Digital Speech Lab at University College London.

Previously, I was a PhD student in the Computer Science department of University College London. I was part of the Centre for Doctoral Training in Cybersecurity. My research project was supervised by Benjamin Guedj and Shi Zhou.
