We are looking for highly motivated PhD/Post-doc candidates in software engineering. The position takes place in a EU-sponsored collaborative project in the field of empirical software engineering and large-scale distributed systems simulation. The project involves inter-disciplinary work with ecology researchers.

Keywords: Software diversity, search-based software engineering, self-adaptive software.
Software systems rely on the interactions between parts: client / server, application / framework / database, apps / mobile platform. The nature of these interactions is very close to mutualistic of trophic interactions between species in ecological systems. However, the species and their interactions are highly diverse in ecological systems (forming an essential component of biodiversity), while software systems are rather homogeneous. Biodiversity is a major component for the ability of ecosystems to adapt in front of unpredicted changes. Thus, in this project, we want to investigate the diversification of software systems to improve their ability to face unpredicted perturbations (attacks, bugs, market evolutions, etc.).
The work will aim at proposing generative mechanisms to dynamically increase software diversity. The major challenges will lie (i) in generating variants that can be integrated in the running system while providing new options for adaptation, and (ii) handling the lifecycle of these variants (when they emerge, when they disseminate or when they disappear). You will collaborate closely with the ecologists in order to develop sound models of diversity dynamics, and with the software engineering researchers to ensure the integration of results in proof-of-concept simulator.
The generation of diverse of software component will reuse recent techniques of software analysis, meta-heuristic search and software product lines, while the runtime integration of diversity in the system will be based on reflective models@runtime platforms.
Our ideal candidate is someone with a background in software engineering, and a keen interest in model-based software analysis, distributed systems or search-based software engineering.
