Create a rigorous, clear and visually strong PhD defence presentation for the thesis “Robust and Trustworthy Federated Learning in Distributed Systems”. The presentation must tell a coherent research story: why federated learning becomes unreliable in adversarial and heterogeneous distributed environments, what research gaps remain, what methods were developed to address them, how they were evaluated, and what the thesis contributes overall. The final deck should feel like an expert researcher’s defence, not a generic AI-generated presentation.
