Laura Arnold is a Lecturer in Linguistics in the School of Culture, History & Language, College of Asia and the Pacific. She specialises in documentation and description of the understudied languages of eastern Indonesia, particularly in the Papuan provinces. Since 2013, she has worked closely with communities in the Raja Ampat archipelago to document their languages. As these languages are endangered, this work creates a lasting record for both the communities themselves and scholars worldwide. She has developed two open-access corpora covering a wide range of linguistic and cultural phenomena; her PhD thesis was a detailed grammar of one of these languages, Ambel. These materials also underpin her theoretical, typological, and historical research. Laura has published extensively on changes in word-prosodic systems (stress and tone) in the Raja Ampat languages, and what these developments reveal about the prehistory of the wider region. She has also drawn on comparative data from across eastern Indonesia to investigate the morphosyntactic expression of possession and spatial relations, contributing to broader debates on language contact, diversification, and change. More recently, she has turned to questions about the social and cultural ecologies in which languages are used, and the implications of these ecologies for language change.
