The main focus of my research is on theoretical phonology, and the demarcation of phonology as a component of grammar relative to morphology and phonetics. Much of my research revolves around harmony systems, in particular consonant harmony, and the more general issue of non-local interactions in (segmental) phonology.
A central topic of interest is the interplay of diachronic and synchronic factors in shaping language structure, and thus the study of processes of phonologization (the emergence of systematic sound patterns from phonetic effects) and morphologization (the extension and/or reanalysis of sound patterns through analogical change).
I am also interested in various issues related to morphological paradigms and their manifestation: inflectional classes, allomorphy, syncretism patterns and paradigm gaps.
Some languages I have worked on include Icelandic (my native language), Faroese (its closest relative), North Sámi (a.k.a. Saami; Finno-Ugric), Turkish, Tsilhqot’in (a.k.a. Chilcotin; Dene/Athapaskan) and Yowlumne (a.k.a. Yawelmani; Yokutsan).
