New Fields for Morphology Workshop

Along with Rachel Nordlinger, I initiated the New Fields for Morphology Workshop which aims to bring together linguists working on the morphology of less widely studied languages who are also interested in morphological theory. The main purpose of the workshop is to engage morphological theory with exciting new empirical data, especially from the Australia + Pacific region. We hope to foster a community of morphologists concerned with both empirical and theoretical issues in Australia and abroad.


I designed and maintain the Yamfinder Comparative Lexical Database Tool and the Southern New-Guinea Lexical Database. This single site is both a tool for the storage and comparison of lexical data across languages as well as the ongoing comparative database for the Southern New Guinea Project.

PhD Thesis

The Ngkolmpu Language, with special reference to distributed exponence.

Ngkolmpu is a Papuan language of the Yam Family, spoken by around 150 speakers in a single village in the Merauke region in the Indonesian province Papua. The language is notable for its extremely complex verbal inflection system which exploits extensive patterns of non-canonical exponence. Most significantly is the extent to which distributed exponence, a relatively unexplored phenomenon, permeates the structure of the verbal system.

This is the first detailed description of this previously undocumented language and is based entirely on first hand fieldwork. It includes a core description of the phonology, morphology and basic clausal syntax. The thesis also entails the most in-depth exploration of the notion of distributed exponence to date. It includes a discussion of the theoretical impacts of this remarkable language and proposes the novel theoretical construct of autonomous sub-paradigmatic organisation to account for the organisational complexity of the language.

My PhD was supported by the ARC Project 'Languages of Southern New Guinea'.
