Career Summary
From 2020-2023, Rob held the position of Research Fellow in Verified Operating System Security with the School of Computing and Information Systems at the University of Melbourne.
From 2016-2020, Rob's PhD with Trustworthy Systems and UNSW Sydney was supervised by Carroll Morgan, Toby Murray, and Kai Engelhardt.
Previously at NICTA and Data61, Rob was a research engineer developing software for the eChronos/SMACCM project, during which time they ported eChronos to the PowerPC e500. Subsequently as a research engineer they developed proofs for the Information Flow project.
Prior to that, they were a software engineer at Open Kernel Labs, Inc. and General Dynamics C4 Systems, where they spent most of their time developing device-driver paravirtualisation stacks for use by Android and Linux kernel instances on a dual-personality smartphone.
Qualifications
Rob holds the degrees of Doctor of Philosophy (Computer Science and Engineering), Master of Information Technology with Excellence, and Bachelor of Engineering (Computer Engineering) with First Class Honours, all from the University of New South Wales.
Recognition and Awards
2021 Australian Museum Eureka Prize for Outstanding Science in Safeguarding Australia, with co-entrants Toby Murray and Mark Beaumont (for research contributions to the Cross Domain Desktop Compositor)
