Key research themes
1. How can computational phylogenetic methods refine the branching and dating of the Inner Indo-European languages?
This research area focuses on applying advanced computational lexicostatistics and phylogenetic algorithms to indo-European linguistic data, aiming to produce refined phylogenetic trees that accommodate linguistic expert knowledge and address shortcomings of previous computational analyses. It matters because accurate branching and dating influence our understanding of Indo-European language evolution and historical linguistics.
2. What phonological mechanisms govern consonant cluster reduplication and dissimilation in Indo-European languages?
Research here investigates the typology and phonological constraints underlying onset cluster reduplication, particularly the dissimilation of consonant clusters such as obstruent+resonant (TR) and sibilant+obstruent (ST) in Indo-European languages. Understanding these mechanisms informs both historical phonology and the characterization of Indo-European morphological patterns.
3. How do sound change and areal interaction influence the proto-forms and evolution of Uralic and Indo-European lexemes, especially concerning consonant clusters like *ks, *kš, and related alternations?
This theme covers the comparative phonological and etymological study of consonant clusters and their metatheses in Uralic and Indo-European languages, focusing on the reflexes of sequences like *ks → *kš in Uralic and their cognates or loans in IE branches such as Balto-Slavic. Significance lies in assessing whether Uralic is a branch of Indo-European or heavily influenced by long-term contact, and in clarifying historical changes like RUKI and sound cluster metathesis.
