My research focuses on developing genomic methods to study populations and communities of multicellular organisms. My group developed the first test for wild animal age based on changes in DNA methylation. We applied this technology to humpback whales and I continue to work on DNA methylation age estimation in this species as well as several other whales, fish, reptiles and seabirds. We have also developed a method for estimating the maximum lifespan of a species from the density of CpG sites in promoter regions of a small set of selected genes. This allows us to tell how long a species might live for from a genome sequence. My goal with these research themes is to develop the field of "genomic population dynamics" to the point where we can estimate most of the key parameters of population biology using genomic tools. 

I have also worked extensively on DNA-based analysis of animal diet and environmental diversity of species with DNA metabarcoding technology. My research group were heavily involved in the early development of dietary DNA metabarcoding. Some highlights of this research were characterising the diets of whales, seals, penguins, whale sharks and giant squid with our new methods; identifying jellyfish as a major food item for seabirds; and developing the molecular methods and conceptual frameworks that made this area a useful research method. My environmental DNA research has investigated species diversity and presence from the poles to the tropics.

In 2020 I will commence teaching a level 4/5 unit on "Environmental DNA sequencing" (BIOL4410) in the School of Biological Sciences at UWA. I will also teach ENVT3307, ANIM3361 and contribute to ANIM2200.
