I am a PhD student in the Weir lab at the University of Toronto. I am studying the phylogenomic history of the skuas and jaegers - a group of seabirds - and the genomic consequences of hybrid speciation in the Golden-crowned Manakin of the Amazon.

Antbirds (Thamnophilidae) are a large neotropical family of passerine bird renowned for the ant-following foraging strategies of several members of this clade. The high diversity of antbirds provides ample opportunity for speciation studies, however these studies can be hindered by the lack of an annotated antbird reference genome. In this study, we produced a high-quality annotated reference genome for the Xingu Scale-backed Antbird (Willisornis vidua nigrigula) using 10X Genomics Chromium linked-reads technology. The assembly is 1.09 Gb, with a scaffold N50 of 12.1 Mb and 17,475 annotated protein coding genes. We compare the proteome of W. v. nigrigula to several other passerines, and produce annotations for two additional antbird genomes in order to identify genes under lineage-specific positive selection and gene families with evidence for significant expansions in antbirds. Several of these genes have functions potentially related to the lineage-specific traits of antbirds, including adaptations for thermoregulation in a humid tropical environment.
