Computing and communication capabilities are increasingly being embedded into physical spaces blurring the boundary between computational and physical worlds; typically, this is the case in modern cyber-physical systems like smart buildings or smart cities. Conceptually, such composite environments can be abstracted into a topological model where computational and physical entities are connected in a graph structure, yielding a cyber-physical space. Like any other software-intensive system, such a space is highly dynamic and typically undergoes continuous change - it is evolving. This brings a manifold of challenges as dynamics may affect e.g. safety, security, or reliability requirements. Modelling space and its dynamics as well as supporting formal reasoning about various properties of an evolving space, is a crucial prerequisite for engineering dependable space-intensive systems, e.g. to assure requirements satisfaction or to trigger correct adaptation.


I am a university assistant at the Distibuted Systems Group at TU Vienna headed by prof. Schahram Dustdar. Previously, I was a post-doctoral researcher 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.
