Computer Science Research Centre.


Research interests

My main interest is bioinformatics in the broad sense, the interface between computing and biology, with emphasis on classification and pattern recognition, especially with regard to botanical taxonomy and systematics. This is a natural consequence of my BSc (Botany), MSc (Plant Taxonomy) and PhD (Cybernetics) studies. I am particularly interested in biological identification and classification techniques, especially those involving the use of artificial neural networks. My current teaching areas are Intelligent Information Systems, Information Systems Development and Computer Logic.
