The problem of engineering dependable software-intensive systems will not go away – it will only become more pressing, as today’s systems are characterized by heterogeneity, are distributed in space and are expected to satisfy functional and non-functional requirements, from safety and reliability to security and privacy. It is clear that if we are going to use ad-hoc methods, we’ll end up with ad-hoc problems. We need techniques for early validation at design time and for tackling uncertainty manifested at runtime.

About

I am Lise Meitner fellow at TU Vienna (EDENSPACE, Austrian Science Foundation). Previously, I was post-doctoral researcher at the Distibuted Systems Group (SmartCT, chair prof. Schahram Dustdar) and at Politecnico di Milano, where I received (2017) my PhD defending a thesis entitled "Modelling and Verification of Evolving Cyber-Physical Spaces". My advisor was prof. Carlo Ghezzi. My research interests lie in the intersection of distributed systems and software engineering, and include dependable self-adaptive and cyber-physical systems, requirements engineering and formal verification.
