My research has been exploring the interface between phonology and phonetics focusing on a range of phonological phenomena (palatalization, assimilation, etc.) and their phonetic correlates or sources (coarticulation, misperception, etc.). I have worked with a number of languages (Russian, Komi-Permyak, Japanese, Kannada, Korean) and employed various experimental methods, including articulography, electropalatography, ultrasound, acoustic analysis, and perceptual experiments.

Phonetics Lab

I am the Director of the Phonetics Lab, which is located on the ground floor of Sidney Smith. The lab is equipped with state-of-the-art hardware and software for audio recording, acoustic analysis, articulatory data collection (electropalatography, ultrasound, electroglottography, electromagnetic articulography), and perceptual experiments.


Since 2007, I have taught a range of undergraduate and graduate courses, mainly in phonetics and phonology, but also in historical linguistics and general linguistics. Here are some of the courses:

  • LIN100 Introduction to Linguistics
  • TBB199 Analyzing speech sounds
  • LIN228 Phonetics
  • LIN229 Sound Patterns
  • LIN362/1162 Historical Linguistics
  • LIN423/1127 Phonetic Analysis
  • LIN1211 Advanced Phonetics (graduate)
  • LIN1224 Advanced Phonology (graduate)
