Houssam Hajj Hassan

Researcher @ Orange | Autonomous Cyber-Physical Systems

I’m an applied researcher specializing in autonomous systems, designing and deploying hybrid AI architectures that combine LLM-based reasoning, causal inference, reinforcement learning, and AI planning to enable intelligent, self-adaptive operation in distributed IoT environments.

At Orange Innovation, I’m currently working on LLM-driven perception and network optimization for autonomous robotic swarms in 6G industrial settings. Experienced technical lead on international R&D projects (ANR, EU Horizon), with a track record of guiding junior researchers from design to deployed systems.
