# PhD position : Proving Correctness of Reconfigurable Systems

The goal of this PhD project is the development of a rigourous design framework for distributed systems, that uses verification from the early stages of model building. Formal verification is the process of transforming a query about the correctness of a system (e.g. is every store request to a cloud treated by storing the data in such a way that any future retrieval request will eventually find it ?) into a logical validity query (is a given formula true in general ?) that can be handled by automated reasoning techniques (theorem proving). Hence, we recognise logic, automated reasoning and model checking as being the main ingredients of formal verification, and also central research topics in our project.

The successful candidate is expected to work on logics for high-level reasoning about parameterized architectures of distributed systems. The decision problems of these logics will be studied from a theoretical point of view, such as existence of proof systems and the complexity of related algorithms. The architecture description logics will be used to verify systems by parameterized model checking techniques based on e.g., invariant synthesis and automata learning. We plan on implementing proof-of-concept prototype tools and performing experiments on models of real-life systems (inter-blockchain communication, mobile applications, etc.)
