I began my biological career and interest as a member of the Junior Naturalists Club in Perth, Western Australia, when I was 10. I completed an Honours degree in Zoology, where I became fascinated by the use of genetic markers (allozymes in those days) to answer ecological questions. As technology has developed, I have continued to use this approach, in particular to understand patterns of movement and dispersal in animals, especially those that inhabit freshwater streams and rivers.
