Pôle Modèles Distributed Computing

Contact: Matthias Függer

We are working on topics from distributed systems, studying their properties and fundamental limitations both from a theoretical and application-oriented perspective.

An incomplete list of current research questions we address in this group is

• Distributed biological systems. Analyzing and designing the dynamics of natural and synthetic biological systems.
• Automated synthesis of distributed systems. Given a specification and a communication model, generate a distributed algorithm that complies with the specification in the given model.
• Distributed games. Multiple agents collaborating or competing against an environment to maximize their payoff.
• Distributed AI. AI to synthesize distributed systems.
• Runtime verification. Monitoring a system during execution to detect anomalies.
