Katerina Papatheodorou is a Researcher at AddressHate and Editorial and Outreach Coordinator at Digital Hate Review, where she builds partnerships and networks across the academic, security, and civil society sectors and works to establish the journal's visibility on a global scale, alongside supporting the editorial and peer review process. A research psychologist, she holds a PhD from Georgia State University. Her work focuses on terrorism, mass violence, and the digital manifestations of misogyny, combining forensic psychology with computational and qualitative methods at the intersection of psychology, security research, and policy. She has spent years studying how extremist actors radicalize and organize across regions and cultural contexts, and led a major study of the incel movement and online misogyny that formed the core of her doctoral research. Her interests extend to how state actors construct and circulate narratives through global media, and to how violence comes to be classified and understood as extremism in the first place. Her scholarship has appeared in Psychology, Crime & Law, Terrorism and Political Violence, the Journal for Deradicalization, and Electronic News, among others.
