Evolutionary biology and zoology



Image: Greg Rouse

I am a biologist interested in the evolution of animal biodiversity.​ I use genetic tools to explore patterns of diversity and to infer the processes that have created these patterns. My research involves population genetic and phylogenetic methods to uncover evolutionary divergences and understand their causes. I use this data to understand the evolution of morphological and life history traits and the geographic distribution of animals.

I am currently a postdoctoral researcher in Guojie Zhang's lab at the University of Copenhagen, where our team is aiming to reconstruct the phylogeny of birds using >300 whole genomes.

In the media & seadragon art

This gallery shows a selection of media coverage of seadragons (mostly of the Ruby seadragon) and, more recently, of work I have contributed to on bird genomics. 
You can also find links to some of my favorite art pieces involving seadragons by skilled artists.

Common seadragon biology

The common (or weedy) seadragon is a marine fish that inhabits the southern Australian coast from Sydney, to Tasmania to Perth in Western Australia. Our work on the common seadragon uses genetic data from hundreds of individuals across the range to investigate phylogeographic structuring. We are particularly interested in investigating the effects of historical processes. Image: Greg Rouse
