I am a full-time senior researcher in Budapest at the Research Institute for General and Hungarian Linguistics, ELTE Research Centre for Linguistics (formerly an institute of the Hungarian Academy of Sciences*) and I also hold a part-time teaching position at the Department of Theoretical Linguistics, ELTE.
My research interests include syntax, morphology, the structure of DP and PP as well as subordination, especially in Hungarian and other Uralic languages. My recently finished Bolyai and Bolyai Plus projects investigated the structure of the Noun Phrase, with emphasis on classifiers in Southeast Asian Languages and Ch'ol (Mayan) as well as on complex numerals and PPs in Hokkaido Ainu (isolate, Japan).
My previous project '(Non-)finite subordination and clause structure' (Sept. 2017 - Dec. 2020) investigated subordination in Old Hungarian, Udmurt and Khanty. This HAS promo video, prepared for the 2017 World Science Forum in Jordan, includes a short interview about my work.
I am founding co-chair of the Hungarian Young Academy. In June 2022, I started a 5-year tenure with the Global Young Academy. In the 2022-2028 period I am a member of the Generative Linguists of the Old World (Glow) Board; since March 2025 I have been serving as the secretary of the Board.
In 2014–2021 served as editor of of Acta Linguistica Academica, an Arts&Humanities journal in Akadémiai Kiadó's portfolio AKJournals.
My name is pronounced as /ˈeːvɔ ˈdeːkaːɲ/.
