I conduct experimental research to explore how prosody affects speech perception and the mental representations of phonetic and phonological knowledge. Some themes in my research are:
- Prosody in tonal and non-tonal languages
- L2 prosody: perception, production, and mental representations
- Documenting prosody in understudied languages and populations
- Social, linguistic, and emotional aspects of prosody

1. Prosody in tonal and non-tonal languages

Basic research into prosodic systems. It addresses questions like:
- How are the variations of duration, pitch, and intensity used to express lexical, sentence-level, and pragmatic meanings cross-linguistically?
- How do speakers process prosody and intonation?
- How are stress and accent represented cross-linguistically?

2. L2 prosody: perception, production, and mental representations

This line of research investigates the role of the native language prosody in a second language, and the prosody of bilingual speakers. It addresses questions such as:
- How do speakers of tonal and non-tonal languages (e.g., Chinese speakers of English) represent pitch in their bilingual lexicons?
- What is the extent of the stress deafness phenomenon?
- What aspects of L2 prosody are the most difficult to learn and why?

3. Documenting prosody in understudied languages, dialects, and populations

Ideally, an unbiased understanding of speech perception is based in a representative sample of languages and speakers. This line of research contributes to this goal by documenting the prosody and segmental contrasts of understudied languages and populations
