Profile

I have a strong interest in evolutionary biology, specifically in IMG_7438the processes underlying
the differentiation of natural populations that ultimately lead to speciation. I am exploring these phenomena using genetics and genomics tools in different pinniped species.

The Galápagos sea lion is an evolutionary young species that shows genetic as well as morphological and ecological differentiation (ecotypes) along an environmental gradient across the Galápagos archipelago despite the absence of obvious dispersal barriers. As such, this species presents a particularly interesting system for studying adaptation and speciation in the presence of gene flow, and the mechanisms driving genome differentiation.

Previous Research and Other Interests

For my PhD project I used population genetics and ancient DNA techniques to investigate the impacts of human arrival on little penguins (Eudyptula spp.) in New Zealand. I also have experience in using transcriptomics for gene discovery in a variety of species. When I am not working I like to go hiking and bird watching.
