To study this I focus on sequencing and analyzing genomes of organisms, especially microbes and using phylogenomic analysis (see my lab site here which has more information on lab activities). (microbe.net)
The two groups came together, and the Avian Phylogenomics Project was born. (sciencemag.org)
His involvement in the Avian Phylogenomics Project — which, apart from appearing at first unrelated to his research area, also requires skills and analysis outside his expertise — is an illustration of this ethos in action. (sciencemag.org)
