Welcome! I am J. Pystynen, linguist and occasional mathematician. This is my research work business card.

My research interests mainly cluster around historical phonology. I am known for expertise in particular on the Uralic family.

Other topics I have worked on (non-exhaustive): etymology, lexicography, historical morphology, phonological typology, diachronic typology;
— Cushitic, Iranic, Dravidian, Yukaghir, Northeast Caucasian, Indo-Uralic, Nostratic, constructed languages

• My researcher ID, with links to my published papers, is ▶ ORCID 0000-0002-4240-0331
• Among my larger projects is ▶ sanat.csc.fi/wiki/EVE-etusivu / Suomen vanhimman sanaston etymologinen verkkosanakirja (Etymological Dictionary of the Oldest Finnish Vocabulary) and its underlying database, of which I am one of the five editors and one of two database designers
