He is the son of the St. Petersburg (Russia)-born linguist and Baltist/ Slavicist Valentin Kiparsky.
These include coining the terms elsewhere principle,[1] and phonological opacity (including the types feeding, bleeding, counterfeeding, and counterbleeding),[2] and creating the frameworks of Lexical Phonology and Morphology (LPM) and its successor, Stratal Optimality Theory.
[3] A noted Pāṇini scholar, he has also made fundamental contributions to historical linguistics[4] and generative metrics, as well as working in morphosyntax, especially on his native Finnish.
Kiparsky was a student of Morris Halle at MIT, where he received his PhD in 1965.
[5] His PhD thesis "Phonological Change" (1965) and his subsequent work on historical linguistics helped form the modern generative view of this area.
