Simin Kargar is a human rights lawyer with a focus on the interrelations of technology and human rights. She studies harmful speech online, gender-based violence and technology, and the interplays of social media, power and new propaganda. In addition, Simin investigates how discourses of geopolitical issues are created and disseminated through social media. Simin has published research analyzing the formation of online movements that led to changes in policies, or to creating tangible social impact. Her current research addresses cyber abuse and online harassment against communities of journalists, artists and activists who - due to their profession, activities or beliefs- are more likely to become targets of coordinated online mobs.
