Short bio

I am currently an associate professor at the University of "Lumière" Lyon 2 and a member of the SID research team within the ERIC laboratory. I earned my Ph.D. degree in computer science in 2016, through a joint program between the University of Bejaia in Algeria and the University Claude Bernard Lyon 1 in France. Before that, I obtained a Magister degree from the University of Bejaia in 2009 and an engineering degree in artificial intelligence from the University of Sétif in 2006. My research spans several key areas in cybersecurity and data management. I focus on secure data collection methods, particularly in resource-constrained environments like the Internet of Things (IoT). I also specialize in key management strategies for ensuring the integrity and confidentiality of communications in these networks. Furthermore, my current work explores the use of graph database analytics, a powerful tool for identifying and mitigating cybersecurity threats by analyzing relationships and patterns in complex data systems.
I am always open to supervising highly motivated students at the undergraduate, master’s, and PhD levels. Feel free to contact me to learn more about potential research projects.
