Background

In 1978 Peter Tischer received a BSc (Hons) in Computer Science from Monash University. In 1983 he completed a PhD in the "The Cyclic Use of Linear Multistep Formulas far the Solution of Stiff Ordinary Differential Equations". In 1982 he became an academic staff member in the Department of Computer Science at Monash University and is currently a senior lecturer in the School of Computer Science and Software Engineering. Since completing his PhD he has developed interests in universal data compression, lossless image compression, image processing and minimal message length inductive inference. He is particularly interested in applying minimal message length principles to image processing. This combination has already led to the development of a method for lossless compression of greyscale images that is currently achieving the best lossless compression of any method reported in the open literature.
