Phd and internship subjects
PhD subjects
Reconfiguration is an inherent aspect of modern distributed systems, such as clouds or IoT. Processes can be created or removed due to internal faults, redistribution of resources, workload or traffic changes. Moreover, the shape of the communication network may change. Self-adapting systems initiate and carry out reconfiguration sequences automatically, in order to avoid expensive or even mission-critical downtimes, required by manual reconfiguration. The successful candidate will develop logics and automated reasoning techniques that enable writing formal proofs of correctness of self-adapting distributed systems. We focus on logics that describe the shape of a network (i.e., the interconnection of processes via communication channels) and how this shape changes with time. Particular attention will be devoted to the implementation of practical verification tools based on automated theorem proving and model checking based on the logics developped in this thesis. To this end, the candidate is expected to work on implementation and prototyping, in addition to theoretical research.
Internship subjects
The goal of this internship is the study of logics for the design and verification of complex component-based distributed applications, using the principles of locality (the ability to describe the effect of an update only from the parts involved while gnoring the ones unchanged) and compositionality (the ability to join the results of local analyses into a global condition capturing the correctness requirement for the entire system). During this internship, the candidate will aquire command of advanced theoretical notions of logics and system verification. The internship comprises theoretical as well as implementation work.
The goal of this internship is to study extensions of finite-state automata over infinite alphabets and apply them to the verification of concurrent and distributed systems with unbounded numbers of threads. The internship comprises theoretical as well as implementation work, and will explore orthogonal domains, such as logic, automata theory and concurrency.
The goal of this internship is to study the combination of Separation Logic with data theories supported by SMT solvers. The internship comprises theoretical as well as implementation work.
