I am a researcher at the Oxford Internet Institute at the Unviersity of Oxford, in Oxford, UK, working on the Computational Propaganda project, in Prof Phil Howard’s team.
I studied for my PhD (currently near submission) in Computer Science at the University of Southampton, UK, in the Web and Internet Science group, supervised by Prof Luc Moreau and Prof Susan Halford. My PhD focuses on causal inference for estimating the social influence of online communications on real-world outcomes, at the individual and at the collective level. My PhD research was honoured with the Best Poster award at the 2016 International Conference on Social Informatics in Seattle, Washington.
I hold an MSc in Operational Research from the University of Southampton (2014, Distinction, dissertation prize, full scholarship), and a BA (Hons) in Computer Science from the University of Cambridge (2012, 2.1, dissertation high commendation).
My research focus is on developing computational models and methods for understanding and analysing patterns of behaviour in online interactions, informed by the social sciences. My research interests relate to the areas of online social influence, causal inference, social network analysis, computational social science, and data science.
