Rob strives to create and study comprehensive models and theories of concurrent processes, thereby answering fundamental questions such as: which problems can be solved in a distributed way, using only asynchronous communication, and which cannot. These insights are applied to the modelling, verification and analysis of distributed systems, in particular to popular routing protocols in wireless mesh networks.

Yanyan is currently researching how to improve the trustworthiness of commodity hardware through software to enable the verified microkernel to be used in situations previously needing an air gap. Multi-core processors are used to provide redundancy and cross-core checking is employed to detect divergence caused by hardware faults. The aim is to increase the trustworthiness of a virtual air gap created by the microkernel, and thus systems running on COTS hardware.

Robert is broadly interested in discovering how one may design and construct software systems with formally proved information-flow security properties at scale. The research focus of his PhD is to determine the requirements for verifying formally that a compiler doesn't break the information-flow security properties of the programs it's compiling – even when those programs use concurrency, and reuse system resources to process information of differing classification levels at different times.
