Leiden University

Esther Theisen holds a BSc in “International Relations and Organizations” (IRO) from Leiden University and will continue her academic path at the University of Glasgow by attending the Erasmus Mundus Joint Master’s Degree “Security, Intelligence and Strategic Studies” (IMSISS).

Her thesis investigated under which conditions online radicalisation leads to political violence analysing the participants of the 2021 US Capitol Riot. In line with this, she previously conducted research at the Norwegian University of Science and Technology (NTNU) on the detection of radical language within far-right online fora, utilising computational and machine learning methods. She presented the findings at the Norwegian Information Security Conference (NISK) 2020. Her overall fields of research are radicalisation, extremism, and political violence, specifically within an online context and focus on far-right groups/individuals. In previous work environments she focused on implementing practices and policies aimed at actively promoting Diversity and Inclusion.
