Dr. Sergio Altuna is a Senior Research Fellow for the Program on Extremism at The George Washington University. His areas of expertise include violent non-state actors in the Great Maghreb and the Sahel; contemporary Islamist thought; Islamist narratives; and the development of alternative narratives and counternarratives. He also specializes in the creation of monitoring and evaluation tools to measure the impact of security policies in unstable environments.

His PhD research focused on the evolution of jihadi narratives, implementing for that purpose an innovative approach based on the compilation, the systematized coding, and the exploitation of an electronic, monolingual, specialized, and diachronic corpus of all relevant propaganda publications by AQIM. Dr. Altuna also holds a BA in Translation and Interpreting from the University of Valladolid, an MA in Arabic Language, Literature, and History from the University of Tunis al-Manar, and another MA in Terrorism Studies from the International University of La Rioja.
