Bertram Vidgen is an OII DPhil student. His research focuses on far-right extremism in online contexts.


Bertie Vidgen is a PhD student at the University of Oxford, funded by the ESRC Grand Union. His work draws on political science theory and computational methods to understand Islamophobic hate speech on social media. His research interests include online political behaviour, political communication and computational social science. He is particularly interested in how advanced methods, such as machine learning and natural language processing, can be used to provide insights into social problems, including extremism, offensive speech and the spread of dangerous ideas.

He has consulted for several companies, designed and taught on courses at the Oxford Internet Institute and organised several conferences and datahacks.
