Biography
I completed my undergraduate and post-graduate studies at Flinders University, and then moved overseas and I held full-time tenured
positions at Carnegie-Mellon University, Pittsburgh, Heriot-Watt University, Edinburgh, Imperial College, London and UIB, Spain before
returning to Flinders as Chair of Computer Systems Engineering. I have also held visiting positions at Bonn University, in Germany, and
the University of the Witwatersrand, in Johannesburg, South Africa.
I also started my own company, and designed a VLSI chip implementing a Zero-Tree wavelet video compression algorithm. This work
produced three US patents, and the company was sold to MediaVision, in Silicon Valley.
Qualifications
BSc(Hons) Flinders University
PhD Flinders University
Honours, awards and grants
FIEAust (Fellow, Institute of Engineers Australia)
Key responsibilities
I run the Embedded Systems and Bio-Informatics research groups in the School of Computer Science, Engineering and Mathematics.
Teaching
Research and consultancy
Research interests
My main research interests are in the area of Integrated Circuit design, Computer Architecture, Image and Video processing and Bio-informatics.
I was one of the first researchers to see the advantages of the wavelet transform for Image Processing, and developed a new class of
image and video compression algorithms, the Zero-Tree coders. These algorithms have proven to be the most efficient image and video
compression algorithms, and my work has been incorporated into the MPEG4 standard, and has been granted several US patents.
In Java, we have developed an incremental tokenization scheme for the J2ME/J2SE method call and storage instructions, reducing class
size by one-half, and execution speed of method calls by a factor of 10-40.
In Bio-informatics, we have developed a new algorithm for Genomic and Proteomic sequence alignment, DASH, which performs 10X
faster than the industry standard BLAST with greater sensitivity. I am currently involved in an Algae bio-fuels project working on
short-read shotgun genome assembly and determining the key genes for bio-fuel production. This work has produced several
international patent applications.
