My main research interests lie in the intersection of theoretical phonology, phonological typology, and the theory of sound change. Using statistical and experimental techniques, I try to estimate which aspects of phonological typology are primarily influenced by diachronic factors and which aspects primarily by synchronic factors/learnability. My work in linguistic phonetics focuses on laryngeal features, temporal relations in speech, and the role of perception and production in phonetic typology. As a historical linguist, I have primarily worked on Indo-European and Austronesian. In Indo-European, my main interests concern phonetic reconstruction, Vedic metric and accent system, and the Slavic accent system; in Austronesian, I’ve conducted research on the peculiar syntactic voice/focus system.
