I started as a lecturer at the University of Otago Computer Science department in 2011. My primary research interest is in distributed systems, and middleware: particularly regarding event-based systems and security. For the official view, I have a departmental staff page. I was previously a Senior Research Associate at the University of Cambridge, and maintain a visiting research fellowship there.

PhD positions that I'm keen to fill!

I am currently seeking to start a number of specific PhD projects, including some in collaboration with other members of the department. Please get in contact with me if you are keen to undertake PhD work, meet the standard of Otago PhD Scholarships, and have research interest that overlap the topics below.

• Comparative performance analysis and optimisation of computer vision code across heterogeneous computing platforms (including multicore, GPU, commodity cloud, dedicated HPC infrastructure, FPGA, etc.).
• Cloud security research (e.g. Information Flow Control in Distributed Event Based Systems).
• Task scheduling analysis, simulation and measurement for massively parallel computing architectures with programmable CPU interconnects.

Note that I am definitely open-minded regarding other topics that overlap my past research.

Teaching

In 2013 I'll be the 300-level course coordinator again, and provide some pages containing relevant information.

Research projects

A number of research projects with which I am involved are listed on the Systems Research Group pages.

I am currently trying to develop techniques for integration of processing into publish/subscribe networks - the Application-Specific Integrated Aggregation (ASIA) project.

More wide-ranging potential research interests

I have perilously broad research and project interests, although they are mostly "systems" in flavour. To provide a non-exhaustive idea of this breadth, and as a starting point for discussion, here are some projects I have been involved with:

• Security in distributed event-based systems, with a particular focus on the use of event-based systems in healthcare applications. This links to security in the Cloud.
• Distributed infrastructure for collaborative research. This has led me to do some investigation of the security of the iRODS distributed storage middleware.
• Green computing, leading into particular interests in virtualisation.
• Network management and measurement tools.
• High dimensional indexing methods for database systems.
• Stream compression of "interesting" data types.
• Declarative and functional programming or systems projects.
• Building monitoring and visualisation.
• Distributed file systems.
• Esoteric website content management systems.
• Efficient IP traffic monitoring.
• Electronic voting systems.

As a general disclaimer, my self-managed webpages are a work in progress (slightly ironic given that I've done past work in website content management systems that should make writing and maintaining such content easy!).
