Louise Wise

Dr. Louise Wise is a Lecturer in International Security with the International Relations department at the University of Sussex (UK). Her forthcoming book (Routledge, 2020) is provisionally titled: An Ecology of Social Death: Colonialism, Ecocide, and the Political Economy of Genocide in Sudan. Her scholarship has won awards from learned societies, and has been recognized for combining in-depth interviews with survivors/victims of genocide from Sudan with conceptual analysis in order to deepen our understanding of the meaning of genocide, as well as its lived experience. Her current research develops a theoretical framework for analyzing genocide by drawing on conceptual tools from complexity theory and assemblage thinking, to reconceptualize the “event” of genocide through an emphasis on its processual, relational, systemic, and international dimensions.

César Estrada Pérez

Born and raised in Mexico, César Estrada Pérez is a PhD Candidate at the School for Conflict Analysis and Resolution. Before coming to S-CAR, he participated in research projects in Spain and Mexico focused on political violence and human trafficking. He teach courses on violent conflict in Mexico, and culture and conflict resolution. His dissertation research examines critically mass violence and the “war on drugs” in Mexico. César’s larger research interests include political violence, mass atrocities and prevention, and narrative approaches to violent conflict.

César’s doctoral dissertation examines the role of conflict narratives in the production of mass violence in Mexico. Drawing on fieldwork in Central Mexico, it examines the dynamics of lethal violence and the discursive mechanisms through which mass killing becomes justified in the public space. Preliminary findings suggest a central relevance of “cleansing narratives” used by perpetrators to justify their killings; this occurs within a context of common association of victims/perpetrators to a “world of criminals”, in which their deaths become “expectable”. This study constructs a dialogue between the field of mass violence and genocide studies, and the narrative approach to violent conflict using the Mexican case.

Christian’s dissertation, Insurgency Resilience and Theories of Al-Qaeda in the Arabian Peninsula, contends that despite the US and allies “war on terror” to eliminate Al-Qaeda after 9/11, Al-Qaeda is currently stronger than they have ever been. What is it about Al-Qaeda that has made them resilient to this onslaught by the most powerful, technologically advanced military the world has ever seen? What causes resiliency in the Al-Qaeda transnational insurgency? The research seeks to determine whether Al-Qaeda and AQAP’s resiliency is caused by their ability to leverage and adapt in relations with the local population groups in terms of norms, customs, and political opportunities to survive and expand the insurgency. This project will seek to theorize the causes of AQAP’s resiliency through fieldwork with the local population groups in south and east Yemen that have engaged directly with AQAP. A locally nuanced perspective on AQAP’s engagement with local population groups will reveal granular aspects to understand the insurgency and their strategy.
