I am an assistant professor in the Linguistics Department at the University of Hawai‘i at Mānoa, and I am interested in how people use and mentally represent the sounds of language. Before coming to Hawai‘i, I was a postdoctoral researcher in the Laboratoire de Sciences Cognitives et Psycholinguistique in Paris. I hold a PhD in Linguistics from the Ohio State University, and an MA (Hons) in Linguistics and English Language from the University of Edinburgh.

I am interested in the phonological processes and representations of the mental lexicon and as such my research sits at the intersection between phonetics, phonology, and psycholinguistics. In my PhD dissertation, I investigated the cognitive source of frequency and predictability effects in spoken language. More generally, I am interested in the ways that frequency, predictability, and other usage-based factors influence linguistic sound structures. My current research examines how factors of lexical organization, such as phonological neighbourhood density, influence speech production and perception. Additionally, I maintain an active research agenda in intonation and prosody, investigating the relationships between predictability, context, and the phonetics of prosodic contrasts.
I use a wide variety of research paradigms, drawing from experimental phonetics, cognitive psychology, and theoretical phonology. There is no "one size fits all" solution to research in the language sciences. This methodological pluralism entails a cross-linguistic approach, which is vital for the advancement of the field, particularly when a key finding is based on data from a small number of languages. Several of my projects involve cross-linguistic studies and diverse methodological approaches.

I welcome enquiries from prospective or current students who are interested in topics related to my research interests. I am teaching two classes in Spring 2019 (click to see course description):
Ling 421: Introduction to Phonological Analysis This course is an introduction to the principles and methods of phonological analysis. Common and less common phonological phenomena in the world's spoken languages are introduced through hands-on experience in working with linguistic data. Major topics covered include phonological and phonetic representations, phonological features, syllable and word structure, and stress and tone. We also cover non-linear phonology and phonological interfaces.
Ling 640F: Sound Change (Co-taught with Bob Blust.)
This seminar explores issues relating to sound change from the perspective of historical phonology. Some issues that may be covered: Is sound change regular? To what extent is sound change phonetically motivated? To what extent is sound change phonologically motivated? Can we predict sound change? What linguistic factors may promote or inhibit a sound change? What extralinguistic factors may promote or inhibit a sound change? What is the locus of sound change? What is the role of language contact? How does the study of sound change inform phonological theory, and vice versa? What can we learn about sound change from laboratory experiments? Students will write a term paper, with several reports throughout the semester. No textbook is required. The prerequisite for this course is LING 421, or consent of the instructors.
Courses I have taught in the past include:
Ling 410: Articulatory Phonetics The purpose of this course is to introduce students to the types of speech sounds found in the world’s languages, and to give them the tools and skills to produce, recognize, transcribe, and analyze these speech sounds in settings of linguistic fieldwork, clinical practice, and/or language pedagogy. Specifically, students:
- Learn about human vocal tract anatomy and how it functions in making speech sounds.
- Receive training in describing, transcribing, recognizing and producing speech sounds.
- Learn what phonemes, allophonesand natural classes of sounds are, and learn to observe basic phonological processes that govern allophonic alternations.
- Gain knowledge about the acoustic correlates of different types of articulations.
Ling 621: Phonology This is a graduate-level course in phonology. The goals of this course are to provide you with a common set of descriptive and theoretical tools for graduate-level work in phonology; to introduce you to contemporary phonological theories; and to build upon your critical thinking and reasoning skills in considering linguistic theory and analysis more broadly. Upon completion of this course, you should be able to follow a phonology presentation at a conference and ask intelligent questions afterwards; find problems and think of ways to search for solutions to these problems after reading a phonology paper; posit multiple analyses for a data set, relying on different pre-theoretic assumptions, and discuss intelligently the drawbacks and advantages of each approach; and think critically about evidence in linguistic theory and how to adjudicate between competing theoretical claims.
Ling 750F: Phonology deconstructed Through readings and discussions this seminar critically examines and reassesses foundational assumptions of phonology, such as phonemes, abstraction, and contrast. Exemplar theory and usage-based models are introduced as supplements or alternatives to traditional generative phonological theory, and we will cover the empirical evidence for and against these approaches. Finally, we consider how our understanding of phonology can be informed by insights from language development within the individual (L1 acquisition), between generations (historical change), and within the species (biological evolution).
