Rachel Walker

Rachel Walker is a Professor of Linguistics at the University of California, Santa Cruz (UCSC), affiliated with the Department of Linguistics. Her research focuses on phonology, phonetics, and their intersections with morphology and psycholinguistics, particularly exploring segmental distribution patterns, harmony systems (vowel, consonant, nasal), and the articulatory basis of complex consonants like liquids. She collaborates on documenting the phonetics/phonology of Ladin varieties spoken in the Italian Central-Eastern Alps.

Key research themes include:
- Long-distance consonantal interactions
- Vowel harmony transparency mechanisms
- Articulatory phonetics of English liquids
- Theoretical phonology (Optimality Theory, Harmonic Serialism)
- Language documentation (Ladin, Kinyarwanda, Menominee)

Her recent work (2020-2024) emphasizes consonant phonotactics in Ladin, privileged positions in vowel harmony, and articulatory coordination in consonant clusters. Over 80 peer-reviewed publications span journals like Journal of Phonetics, Phonology, and Language, along with influential books such as Vowel Patterns in Language (2011). She holds a PhD in Linguistics and has advised graduate researchers on phonological fieldwork and theoretical analysis.
