About Me

I’m a Lecturer in Phonetics and Sociolinguistics at the University of Glasgow. My research is in sociolinguistics, phonetics and speech perception, and I’m interested in how the social aspects of speech communities affect how speech sounds are produced and perceived.

My expertise is in Scottish English (especially phonetic variation in Glasgow), rhoticity, and cross-dialect perception, and I have also worked on perception of speech tempo and phonetic reduction.

I am most skilled in: Phonetics teaching, Sociolinguistics teaching, R, Praat and Perception experiments

Employment

Lecturer in Phonetics and Sociolinguistics

University of Glasgow

2021 - 2022

English Language and Linguistics

I am delivering teaching, supervision and assessment on theoretical, instrumental and articulatory Phonetics (segmental and prosodic approaches), variationist Sociolinguistics, and general linguistics at all levels from Level 1 to PGT. I am course convenor for both Honours PGT Sociolinguistics courses, as well as the Level 2 year group for the linguistics department.

2020 - 2021

Changing /r/ accents? Towards a sociophonological understanding of sound change

We used a variety of methods to investigate residual rhoticity in Blackburn, Lancashire (where many speakers still pronounce the /r/ in words like car and third), examining the mechanisms by which it is changing over time.

Research Fellow

University of Leeds

2017 - 2020

Speech tempo perception and missing sounds

In this project we investigated the link between laboratory measurements of speech tempo and how listeners perceive speaking rate. I designed and ran a suite of speech perception experiments, maintained a large phonetically-aligned corpus, and contributed to analysis, conference presentations and journal submissions.

Research Assistant

University of Glasgow

2012 - 2017

While completing my Phd I worked on multiple funded projects run by researchers from different universities. Tasks included:

  • Statistical analysis, transcription work
  • Writing contributions to research outputs
  • Participant recruitment and recording
