Research Statement

My research focuses on engineering intelligent systems capable of autonomous reasoning and strategic support in high-stakes environments by integrating mathematical foundations with causal inference and reinforcement learning. A central theme is the design of Multi-Agent Reinforcement Learning (MARL) architectures that are physics-informed, meta-learned, and hybrid — enabling robust coordination in complex, adversarial, and partially observable settings. Complementing this, I develop Expert Systems and explainable AI frameworks that translate learned policies into interpretable, actionable intelligence for domains including cyber defence, financial markets, and adaptive education.
