Research:

I am interested in how evolutionary processes vary spatially across the globe. Comparative approaches are used to determine how rates of evolution vary across latitudinal gradients and in regions differentially affected by Pleistocene climatic cycles. My lab uses a variety of genetic, field and computational approaches within a phylogenetic framework to estimates rates of speciation, extinction, and evolution in species discrimination traits (e.g. bird colour, bird and frog song). Next generation sequencing methods are used to investigate genome wide rates of introgression across avian hybrid zones and to map traits important for speciation in boreal, temperate and tropical faunas. Using such data, we address whether evolution proceeds fastest in species rich or species poor environments and whether climate change was instrumental in accelerating evolutionary rates.
