I study how to create good materials for second language learning and tests for assessing second language ability, and particularly how technology can be used to for language learning and testing. My work on using technology for language learning has led me into many facets of applied linguistics including the study of grammar and lexis, multimodal communication, language ideology, and language assessment. I connect students to the professional world of applied linguistics by selecting readings and making assignments that allow them to engage with important issues in the field.
