My love for linguistics stems from a love of discovering patterns in how people use spoken and written language in context. I seek explanations for why such patterns exist and how they might develop over time, especially explanations that are based in communicative function, general cognitive principles and historical development.
In general, I ask: What linguistic structures do people have at their disposal, and how do they use them for particular communicative purposes in particular pragmatic contexts? One main area of my main research looks at probabilistic case marking, in which speakers appear to have the "option" of using case markers that contain semantic and syntactic information under certain pragmatic conditions. Another key area of my research examines how speakers of tone languages use pitch for conveying both lexical and (more context-dependent) intonational information.
To answer these questions, I take an interdisciplinary approach that uses a mix of traditional linguistic field methods and quantitative methods, including experimental and corpus-based approaches. I work mainly with primary data that I have collected through fieldwork conducted in India and Nepal or through collaborations with colleagues. My publications include work in acoustic phonetics, speech perception and grammatical descriptions of aspects of under-described languages.

Recent and ongoing projects
SÜMI CORPUS DEVELOPMENT
What semantic and discourse pragmatic factors influence the use of probabilistic case marking of noun phrases? For my dissertation, I compiled a small spoken language corpus of Sümi consisting of short narratives, interviews and video description tasks that were recorded, transcribed, translated and tagged with Dr Salome Kinny (ICFAI). Funded by the National Science Foundation (DEL-DDRIG 1723519) [link]. With Scott DeLancey (Oregon).
How different are languages? How might we measure cross-linguistic differences along a specific grammatical feature? In this project, I use parallel text data to quantify differences in core case marking patterns across various Tibeto-Burman languages.
INTERACTION BETWEEN TONE & INTONATION
Differences in pitch are used to convey both lexical tone and intonation information. How might they interact in languages with simple tone systems? What consequences are there for lexical tone perception? In this project, we show how words in Yolmo and Syuba, two language varieties of Nepal, can accommodate both types of information. With Lauren Gawne (La Trobe Uni) & Melissa Baese-Berk (Oregon). [GitHub link]
TENYIDIE TONE: VARIATION & CHANGE
Five level tones is often taken to be the maximum possible number of contrasts in a language. Tenyidie/Angami (Nagaland) has been described as having five such tones. In this project, we provide the first acoustic description of the tones, comparing productions from older and younger speakers living in Kohima. With Priyankoo Sarmah (IIT Guwahati) & Mimi Ezung (Nagaland University).
SÜMI LANGUAGE DOCUMENTATION
November 2010 - October 2012
Principal investigator, worked with the Sümi Cultural Association to document traditional agricultural songs and stories of the Sümis (Nagaland, North-East India). Funded by the Endangered Languages Documentation Programme (ELDP) and the Firebird Foundation for Anthropological Research. Data available at Endangeed Languages Archive (ELAR) [link].
SÜMI LITERACY DEVELOPMENT
October 2012 - June 2014
Main organizer of a mother tongue literacy workshop held in Zunheboto town with the Sümi Literature Board and North-east Literacy Network to develop children's books in Sümi. Supported by the Foundation for Endangered Languages.
