Academic qualifications

Bachelor of Applied Science (Conservation of Cultural Materials), University of Canberra, 2000
Bachelor of Marine Science (Hons 1A), Macquarie University, 2005
PhD (Zoology), University of Otago, 2009

Research interests

  • Biogeography: how physical processes (such as earthquakes and volcanoes) influence spatial patterns of biodiversity
  • Long-distance dispersal, e.g. of coastal marine organisms and their pathogens / parasites
  • Antarctic and sub-Antarctic ecology and evolution
  • How density-dependent processes influence spatial biodiversity patterns

My group combines molecular ecology with aspects of earth sciences to understand the processes that shape global patterns of biodiversity. We use a wide range of techniques to address research questions, including genetics (e.g. metabarcoding and phylogenomic analyses), and ecology, and have a particular focus on the high-latitude ecosystems of the Southern Hemisphere (New Zealand, the sub-Antarctic and Antarctica). Examples include studying how kelp communities and parasites can raft long distances across oceans, how plants and animals probably survived past ice ages by sheltering around volcanoes (and in volcanic caves), in Antarctica, and how large disturbances such as earthquakes create opportunities for genetic and community change in marine ecosystems in New Zealand.

I am also a member of the Coastal People: Southern Skies collaboration that connects communities with world-leading, cross-discipline research to rebuild coastal ecosystems.
