Her teaching has revolved around the areas of middle and secondary students’ English language learning in the U.S. and Asia, K-16 foreign/heritage language instruction, and graduate-level courses in TESOL and literacy education. Her major research interests include English language learners’ literacy learning, with most of her research focusing on adolescent multilingual students’ literacy practices in and outside of school and their identity construction. She has recently examined issues around digital and multimodal literacies of multilingual students (including their navigation between print-based and digitally-mediated multimodal literacies) and ESOL teachers’ perceptions, experiences, and implementation of multimodal literacies and technology in the classroom.
