Biography

  • 1992: Came to NZ with the equivalent of a BSc from Germany. Undertook MSc studies in physics at the University of Auckland. The thesis was about signal processing for underwater acoustics used in a climatology experiment.
  • 1994: Graduated MSc with 1st Class Honours. Later in that year, I started a PhD under Mark Titchener, on T-Codes.
  • 1998: Finished PhD thesis and started my own consulting company, Technology Transfer Consulting Ltd. Did a bit of web work and more technical translations than you could shake a babelfish at. Customers include The University of Auckland and O'Reilly, Germany, for whom I translated Jerry Bradenbaugh's "JavaScript Application Cookbook" into German, as well as a number of chapters from "Perl in a Nutshell". Graduated with my PhD at the end of the year.
  • 2000: Got bored with just business and decided to get back into academia. That's why I'm here.

Research | Current

  • Anything that's fun!
  • Network coding over satellite and other long latency links
    Did you know that Internet via satellite often doesn't use the expensive satellite link very efficiently? Network coding can potentially help, but in order to get there, we need to experiment a lot. For this purpose, we operate the Auckland Internet Satellite Simulator.
  • T-Codes and T-information theory
    To understand T-information theory, you'll need to understand T-Codes. To understand T-Codes, you must first understand T-Codes. If this confuses you, talk to me.
  • Complexity in time series data and the use of information measures in detection and decision-making, e.g., in the detection of network events or similarity comparisons in noisy data
  • Sustainabilty of real-time protocols on the Internet
    Ever wondered why VoIP applications such as Skype seem to continue to (just) work on Internet infrastructure that wasn't built for it? So am I.
  • Web application programming and security
