About me

I’m a researcher in computational linguistics based in Slovenia. My main research areas are corpus linguistics and natural language processing. I focus on implementing quantitative and statistical methods in the research of linguistic data, and compile language resources and datasets for Slovene and other languages.

So far, I’ve worked in several different subfields, including computational morphology, digital lexicography, research on spoken language and computer-mediated communication, computational dialectometry, quantitative syntax analysis, computational phraseology, and large language model development (particularly through the compilation of instruction-tuning datasets).

I’m strongly in favor of empirical and data-driven research that brings about open-access and directly applicable results to the benefit of everyone.
