He leads the Software Systems Group. His main area of expertise is software and systems testing, particularly applied to autonomous- and variability-intensive systems. He has recently investigated the application of software and systems testing techniques in quantum computing and has co-authored the first property-based testing technique and tool for quantum programs. He has also been the Principal Investigator of the STFC Proof of Concept Project on Property-Based Testing of Quantum Programs (2020-2021); the past project concerned simple input-output behaviour of quantum circuits and did not consider any reliability or decoherence. The present project builds upon the expertise of Mousavi in testing and monitoring dynamical systems and transfers them to the area of quantum computing.
