Research interests

I've been fortunate to be involved in a wide range of interesting research projects that have used molecular genetic techniques to learn about animal population ecology. I started my university education in Canada, followed by a few years working in a laboratory investigating population genetic structure in Pacific salmon. After moving to Australia I enrolled in a PhD program at the University of Tasmania. My thesis focused on studying the diets of various marine predators by characterising the prey DNA present in faecal samples. This included research on the foraging ecology of macaroni penguins as part of the Antarctic Division's 2003-04 Heard Island ecosystem study. On completing my PhD (2006) I held an NSERC post-doctoral fellowship at the University of Victoria, Canada (2008-2011) and then an RJL Hawke post-doctoral fellowship at the Antarctic Division (2011-2014). In these positions I primarily worked on evolutionary genetics of stickleback fish and the genomics of Antarctic krill, respectively.

Since 2014 I have been working as a research scientist within the ecological genetics group at the Antarctic Division. I am currently involved in continuing studies of animal diet (primarily penguins and seals) and Antarctic krill ecological genetics (population structuring and genetic responses to CO2-induced stress). I am also excited to be coordinating a new Australian Antarctic Science project that is investigating Southern Ocean plankton biodiversity using high-throughput DNA sequencing. This will include studies characterising communities of single-celled protists and zooplankton, and the bycatch species component of the Antarctic krill fishery.
