My primary research agenda emphasizes the attainment of intelligible speech for additional language speakers, inclusive of both speaker- and listener-based variables. Specifically, I take into account the linguistic and intercultural considerations that define native-nonnative and nonnative-nonnative interaction. Given the increased global spread of English, much of my current research is informed by scholarship derived from Global Englishes (inclusive of world Englishes, English as an international language, and English as a lingua franca). Additional foci include the effectiveness of language preparatory courses in international students’ academic and social adjustments during university study and the promotion of methodological rigor within applied linguistics research. 

My recent publication in the Journal of Second Language Pronunciation received the journal’s Best Doctoral Student Paper Award (Crowther, 2020), while my co-authored publication in Studies in Second Language Acquisition was shortlisted for the International Language Testing Association’s 2018 Best Article Award (Crowther, Trofimovich, Saito, & Isaacs, 2018). I recently received a University of Hawai’i Endowment for the Humanities 2020 Summer Research Award worth $3,500 to develop a foreign language speech corpus for intelligibility research.

As an experienced English language instructor, my long-term scholarly objective is to link research to pedagogy. As an early academic who has greatly benefited throughout my graduate studies from the collaborative opportunities afforded to me, I recognize the value of providing similar hands-on guidance and opportunities to my current and future students.

Areas of Expertise

  • Second language speech perception (inclusive of both speaker and listener variables)
  • Mutual intelligibility in multilingual & multicultural interaction
  • Global Englishes (inclusive of world Englishes, English as an international language, English as a lingua franca)
  • Methodological practices in applied linguistics (specifically SLA) research
