Ranjan Sen is a Lecturer in Linguistics in the School of English, University of Sheffield. His main research interest is sound change, focusing particularly on developing techniques to reconstruct and account for phonological change over time, and investigating to what extent synchronic structure plays a role in diachronic phonology. He is the author of 'Reconstructing phonological change: duration and syllable structure in Latin vowel reduction' (Phonology 29, 2012), 'Exon's Law and the Latin syncopes' (in Philomen Probert & Andreas Willi (eds.), Laws and Rules in Indo-European, OUP, 2012), and 'Diachronic phonotactic development in Latin: the work of syllable structure or linear sequence?' (in Charles Cairns & Eric Raimy (eds.), Handbook of the Syllable, Brill, 2011).
