Robert Sison
PhD Student

Research Interests

Robert is broadly interested in discovering how one may design and construct large systems with formally proved information-flow security properties. His current research focus is on determining how one might go about verifying formally that a compiler doesn't break the information-flow security properties of the programs it's compiling, even if the programs are using concurrency.

Robert is a third-year PhD student supervised by Toby Murray and Kai Engelhardt.

For his machine-checked Isabelle/HOL formalisation of a concurrent value-dependent noninterference-preserving compiler, please see the COVERN project.
