About Me

About Me

I am a Ph.D. Candidate in Cloud Security at Université de Constantine 2, specializing in distributed cloud architectures, IoT systems, and real-time AI. My research focuses on fault-tolerant distributed infrastructures and intelligent access control for smart environments.

I have published work on multimodal violence detection combining physical actions and emotional cues, bridging AI, security, and human behavior analysis.

As a software engineer and educator, I develop cutting-edge solutions in IoT and distributed systems while teaching the next generation of developers about AI, Machine Learning, and modern software development practices.

Currently, I’m working on my Ph.D. thesis: “Development of Secure Integrated Systems for Smart Campus” at the MISC laboratory.
