I am a computer scientist by training. I carried out my doctoral research at the Department of Computing, Imperial College London, in the United Kingdom. I studied under the supervision of Prof. Susan Eisenbach and Prof. Sophia Drossopoulou as part of the SLURP group and Distributed Software Engineering Group (2004 to 2008).
I was a researcher at, and partly funded by, the AETHER project, part of the EU’s Future and Emerging Technologies programme, studying self-adaptive embedded systems for pervasive computing (2005 to 2008).
I am interested in the design and implementation of concurrent object-oriented languages.
AETHER (2005 – 2008), European Commission (EC) integrated project under the Community Research and Development Information Service (CORDIS), Information Society Technologies (IST), Future and Emerging Technologies (FET), 6th Framework Programme (FP6). Coordinated by the French Atomic Energy Commision (CEA) with 14 partners from 9 countries and a €6M budget, the project involved research in self-adaptive embedded systems for pervasive computing.
My research focused on concurrency and message passing, scheduling and fairness, and programming language design and virtual machine implementations.

My research focused on modern concurrency abstractions for object-oriented programming languages (chords and the join calculus), and scheduler specifications and guarantees of liveness, fairness and runtime performance.
