Past

Bernard was a graduate researcher with the Software Systems Research Group at NICTA and a PhD student at the University of New South Wales. He worked on the construction of dependable multi-criticality real-time systems. This incorporated aspects such as performing worst-case execution time analyses of OS kernels, and exploring the interactions between formal verification and real-time behaviour.

Career Summary

Bernard was a developer at Open Kernel Labs, working on the OKL4 microkernel. He also has worked for for Tieline Technology, developing embedded DSP-based audio/video systems. Until recently, Bernard was the Director of Training for the Australian Informatics Olympiad Committee.

Qualifications

Bernard was awarded a PhD from the University of New South Wales, having worked as a graduate researcher with the Trustworthy Systems group at NICTA. His thesis examined the ingredients for building trustworthy mixed-criticality real-time systems with formal verification and static analysis. Bernard also holds a BE (Electrical Engineering) with first class honours, and a BCM (Computer Science, Pure Mathematics), both from the University of Western Australia.

Affiliations

Bernard was an organiser of the 2013 International Olympiad in Informatics, which was held in July 2013 at the University of Queensland.
