Charles Nagle is Assistant Professor of Spanish and Coordinator of the Lower-Division Spanish Language Program at Iowa State University. He received his Ph.D. in Spanish Linguistics from Georgetown University (2014).

Dr. Nagle teaches courses on Spanish language and linguistics and applied linguistics. He enjoys engaging students in practical, data-driven activities that encourage them to explore and develop their own interests. His main area of research is in second language (L2) phonetics and phonology and individual differences. In broad terms, his work examines L2 pronunciation development as a dynamic process that changes in response to a range of factors, including the type, quantity, and quality of instruction that learners receive and their goals for language learning. His other interests include attitudes towards pronunciation instruction, the place of pronunciation in the foreign language curriculum, and research methods in second language acquisition (SLA), particularly longitudinal approaches to SLA and the application of advanced statistical models to SLA data.
