I received my PhD in linguistics at the Ohio State University in 2004, working with Elizabeth Hume. From 2004 to 2006, I was a postdoc in the Arizona Phonological Imaging Laboratory (APIL), directed by Diana Archangeli. From 2006 to 2012 I worked as an assistant and then associate professor in the Linguistics Department at the University of Ottawa, before joining the linguistics program in the English department at NCSU in the fall of 2012.
Teaching and Research Interests
I study linguistic sound patterns using laboratory and computational techniques. Sound patterns are of interest because they are fundamentally arbitrary, so they are a good testing ground for studying the interaction of physiological, cognitive, social, and other factors. Different sound patterns reflect these influences to different degrees. Currently I am especially interested in covert articulatory differences and how these relate to linguistic variation and change. I am also interested in segmental phonology, and the use of distinctive features to model it, as well as idiosyncratic phonological patterns, such as English /r/ allophony, and phonological differences between Autistic and unaffected populations.

Phonetic factors and individual differences in the inception of sound change: The development and spread of changes in pronunciation norms provide a valuable opportunity to investigate the interaction of group-level and individual-level factors related to language. One ongoing project concerns a sound change in progress in Canadian French.
For many French speakers in Southwestern Quebec and Eastern Ontario, the final vowels in words such as heureux, docteur, and commun are pronounced with a rhotic ("r"-like) quality similar to English [r]. These variants have emerged since the mid 20th century, and this project tracks its development in order to shed light on the role of phonetic and individual differences in the inception of sound change. This project has three parts:
1. Automatic transcription and acoustic analysis of two conversational speech corpora housed in the Sociolinguistics Laboratory at the University of Ottawa, tracking the change in 75 speakers of French in Gatineau, Quebec born from 1893 to 1991.
2. Articulatory and acoustic analysis of laboratory speech, using ultrasound imaging to generate real-time video of tongue movements, revealing that rhotic vowels are articulatorily similar to English [r], and show similar inter-speaker articulatory variation.
3. Perception study of rhotic and non-rhotic vowels by English and French speakers in Ottawa, English speakers in Raleigh, and French speakers in Paris (with Jeffrey Lamontagne, University of Ottawa).
Articulatory signals from ultrasound video: This project develops a technique for extracting time-varying articulatory signals from raw untraced ultrasound video (with Christopher Carignan)
Individual phonological differences: This project investigates the role of Autism Spectrum Disorders and autistic traits in the specificity phonological representations (with Kuniko Nielsen, Oakland University, and Lyra Magloughlin, University of Ottawa)
P-base: P-base is a database of several thousand phonological patterns in 549 languages and multimodal phonetic data on the production of 130 crosslinguistically frequent consonants and vowels.
