Dr. Ziad Al Achkar

Graduated 2023
Dissertation: Humanitarian Action in a Digital World: How the Pursuit of Legibility Shapes the Humanitarian Act.

Website: https://www.ziadachkar.com/

Dr. Ziad Al Achkar’s research focuses on the use of digital technologies and remote sensing by humanitarian and peacebuilding organizations. He looks at the role that legibility plays in this sector, and how to develop and design responsible and ethical practices. His dissertation focuses on the pursuit of humanitarian legibility, how through technology, quantification methods, remote sensing, and other Information Communication Technologies, humanitarians made the world and the people they work with more legible, identifiable, and monitorable. In the dissertation project, he investigates three questions: First, how has digitalization and data changed or influenced the work humanitarian do? Second, how do partnerships with the private tech sector play a role in the humanitarian space, and what their influence is? Third, and lastly, but critically, is to understand the relationship between local communities and modern digital humanitarian action, or in other words, what does localization looks like (and what it ought to look like) in an increasingly digital humanitarian world?


Dr. César Estrada

Graduated 2020
Dissertation: Genocidal Mexico: The Unfolding of Mass Violence, Radical Categorization, and the Narratives of the “War on Drugs”

Placed, Post-Doc Fellowship, University of Notre Dame

Personal Website

Born and raised in Mexico, César Estrada earned his PhD in 2020 at the Jimmy and Rosalynn Carter School for Peace and Conflict Resolution. César is currently Fellow at the Kroc Institute for International Peace Studies and the Kellogg Institute for International Studies, at the University of Notre Dame.  Before coming to Notre Dame, he served as a Director within the Unit of Policies and Strategies for Peacebuilding at the Secretary for Security and Citizen Protection in Mexico.  

César’s doctoral dissertation examined 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. The final study documents 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.
