About me

I am an evolutionary biologist fascinated by genetic, linguistic and cultural diversity. My interests concern what has caused the areal variation that we can see today in populations of humans and other species. What has driven or inhibited populations differentiation or contacts? What does the contemporary variation tell us about the past? In my PhD I studied phylogeoraphy and speciation of ants in the Palearctic region. During my postdoc I have been applying population genetic framework to linguistic data, and studied Uralic languages, Finnish dialects, spoken language in Helsinki, written language in Kotiliesi, and compared Finnish east-west division in genes, language and culture. Our aim is to use data from different field to create a holistic view about the human past in the Uralic speaker area and to understand variation and change in different kinds of data on human diversity.
