News: I will be presenting on May 18th at the Interfaces of Phonetics conference organized virtually by the Carl von Ossietzky Universität Oldenburg.
I am a postdoc at the University of Oxford working with Aditi Lahiri on the project, "Complexity in Derivational Morphology: Theory and Experimental Evidence." This project is in collaboration with Carsten Eulitz, Frans Plank, and Anna Gupta at the University of Konstanz, and seeks to clarify how derivational complexity in word morphology is processed in the brain, and how present synchronic data can be linked to the historical development of the lexicon in Germanic languages.
Complexity in Speech Systems
The study of speech as a complex system considers articulatory, acoustic, and perceptual structure to be an emergent function of communicative interactions between higher-order units (e.g., patterns in success/failure to transmit a given message).
This approach requires that the speech system reflects the fundamental heterogeneity of distributions of contrast in higher-order units in the language, and therefore requires phonetic data to be much broader in scope (e.g., cross-linguistic comparisons would not be between controlled elicitations of phones, but between large databases of words or other higher-order units in each language).

My work on speech production has focused primarily on obstruents, and in particular on the contextual asymmetries and points of instability that are a hallmark of such systems.

Expanding the Scope of Data on Understudied Languages
The need for a broader linguistic base for research on human language production and perception is well-known and readily acknowledged.
Two major gaps that remain are in the availability of computational resources and perceptual data for understudied languages. Regarding the latter it is of particular importance that such languages serve as grounds for both replicating existing psycholinguistic findings and generating new ones.
