PhD in Computer Science, Thomas is currently taking part in European project PLAY, dealing with distributed enterprise service buses (ESB). Thomas's work focuses on different models of distributed computing in the context of anonymous networks, finding solutions for problems such as leader election, enumeration/naming and distributed snapshot. He also works on ubiquitous computing and adaptive applications topics. The final goal is to provide a generalized way to conceive communication applications over heterogeneous networks.
