language contacts, phylogenetic linguistics, historical linguistics and lexicology


Location: Szeged, Hungary

During my undergraduate years, I studied Finno-Ugric linguistics which introduced me to various Uralic languages, their structure, and developments. I have also been lucky to travel the Finno-Ugric world making friends and learning not only languages but also something about the cultures of their speakers. As a student, I mainly worked as a Finnish language teacher but in 2015 I began compiling information for Bedlan’s datasets. After graduating with my masters, I had been introduced to the world of large datasets, phylogenetic linguistics and quantitative methods in general. Currently, I’m a PhD student at Uppsala University, Finno-Ugric languages which is part of the Department of Modern Languages. During 2021-2022 I teached at the beautiful Rauma campus (Faculty of Education, University of Turku). From 2022 onwards I’m working as a visiting lecturer of Finnish language and literature in Szeged (Faculty of Arts, University of Szeged, Hungary.

In my project, we bring the theme of language contact to the phylogenetic context and use this information to study the timing hypotheses given to the Uralic language family.

I’m a linguist working in a highly interdisciplinary team. My background in teaching has helped me to explain linguistic concepts to other members and collaborators. In return, I have had the opportunity to dip my toes into the pool of other sciences such as genetics, archaeology and geography.

When not working on papers, I enjoy computer games, writing stories and taking long walks.
