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.

Comparison of seadragon anatomy

This figure shows X-ray images of the skeletons of the leafy, common and ruby seadragon (from top to bottom). Comparing these images helped us identify characteristics of the skeletal system that distinguish the ruby seadragon from its relatives.
