The Genomic Landscape of Phylogenetic Variation


Phylogenetic thinking is one of the most important pillars of modern biology. The ability to frame biological questions in the context of common ancestry and shared inheritance underpins not just evolution, but also fields as wide-ranging as forensics, epidemiology, conservation, and medicine. In recent years, genome-wide sequencing has presented both extraordinary new opportunities and new challenges for phylogenetic inference. By radically increasing the amount of data that can be collected quickly and cheaply, new sequencing technologies continue to unlock a wealth of information that can be brought to bear on questions about phylogenetics and molecular evolution. However, these massive datasets can be messy, complicated, and difficult to interpret. My research focuses on how to make the most of the newly unearthed information, while avoiding new pitfalls. In this talk, I will discuss several related efforts I have undertaken with students and collaborators to understand how and why phylogenetic information varies across genomes, how this variation relates to the underlying processes of molecular and genomic evolution, and how a phylogenetic perspective can be used to address questions of both fundamental and applied importance.
