primary research interests

  • variation in speech production and perception
  • psycholinguistics of bilingualism (i.e., crosslinguistic influence, perceptual learning, talker identification and discrimination, listener biases, etc.)
  • bilinguals as a locus of contact-induced sound change
  • probabilistic reduction as an outcome of linguistic experience

selected research methods

  • corpus phonetics
  • experimental design (lab/online)
  • bayesian statistics
  • exploratory data analysis
