Research

I use the tools of comparative phylogeography, phylogenetics and historical biogeography to study the genetic consequences of historical events (e.g., climate change, habitat fragmentation, population range fluctuation) for species in arctic (or subarctic) and alpine environments. I have a particular interest in exploring the co-evolutionary histories of species that share tight ecological associations (e.g., hosts and their parasites), and though I am a mammalogist at heart, I have come to appreciate the beauty of a well-preserved tapeworm! In the DeChaine Lab I am expanding my taxonomic comfort zone to encompass arctic and alpine flora.

A friend and colleague, Dan Rabosky, introduced me to programming in R while I was at Cornell. Despite Dan's best efforts I'm still not much of an R programmer, but I have put together some useful tools for automating certain tasks in phylogenetic analyses. You can find them here.
