I am a Ph.D student in Applied Linguistics and Technology at Iowa State University.. I am also a Teaching Assistant at ISU, and I teach First-Year Composition courses for undergraduate students, ESL courses for undergraduate and graduate students, and academic writing for graduate students. I have taught English as a Foreign Language for over 17 years at different language institutes, programs, and at the Federal University of Viçosa. I have also taught ESL at the Alabama Language Institute in Gadsden, Alabama. As for research, I am interested in CALL, language assessment, material design, and technology applied to language learning and teaching, especially to pronunciation instruction.
