I am a PhD student in the LACOLA project ("Language, cognition, and landscape", see the link below) in which we investigate how people categorize and talk about the landscape, i.e. the "geophysical environment". In this project we look at several languages from around the world, and my focus is Germanic languages, especially Övdalian, a vernacular spoken by about 1,500 people in central Sweden.
Linguistic categorization was also the topic for my BA thesis. I wrote about how the human body is categorized and talked about in the Austroasiatic language Kammu. My MA thesis had a more theoretical approach, and looked at how semiotic theories can shed light on linguistic iconicity.
