PhD Student; UNSW Sydney

Research Interests

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.

Career Summary

Previously at NICTA and Data61, Robert was a research engineer developing software for the eChronos/SMACCM project, during which time he ported eChronos to the PowerPC e500. Subsequently as a research engineer he developed proofs for the Information Flow project.

Prior to that, he was a software engineer at Open Kernel Labs, Inc. and General Dynamics C4 Systems, where he spent most of his time developing device driver (para)virtualisation stacks for use by Android and Linux kernel instances on a dual-personality smartphone.

Qualifications

Robert holds a Master of Information Technology with Excellence, and a Bachelor of Engineering (Computer Engineering) with First Class Honours, both from the University of New South Wales.
