Employment history
Programmer, software engineer, systems analyst (1986-1995)
PhD student (1996-1999)
Research Scientist, Museum Victoria (1999-2001)
Senior Curator of Marine Invertebrates, Museum Victoria (2001-present).

Research Interests
Marine biogeography, macro-ecology and macro-evolution; marine conservation biology; and taxonomy and evolution of echinoderms (sea stars, brittle stars, feather stars, sea cucumbers, sea urchins).

Overall, the research is focused on using the vast amounts of data and tissues stored in museum collections to address issues of biodiversity management.
