My current research interests are the field of real-time systems, mostly on estimation of upper bounds of execution times of tasks (what we call in the community WCET estimation – Worst-Case Execution Time Estimation). You may also be interested by our open-source static WCET estimation tool Heptane.
My former research interests included distributed systems, parallel programming, distributed shared memories and fault-tolerant systems. Over the years I’ve worked on distributed systems (PhD thesis on distributed garbage collection in object-oriented languages), parallel systems (Distributed Shared memories), fault-tolerant real-time systems.
I am « Habilitée à Diriger des Recherches » since november 2001 (listen to my talk – sorry, I speak french -, get the document describing my research activities – also in french, have a look at the pictures).
