My research broadly focuses on speaking and writing assessment. My specific research interests include scale development and validation, rater behavior and training, psycholinguistic approach to language testing, assessment literacy for language teachers, and test score use in educational settings. In most of my research, I employ a largely linguistic approach to examining characteristics of speaking and writing performances, to help better understand the construct of language proficiency, psychometric qualities of test scores, and validity and fairness evidences for language tests.
At UIUC, I direct the English Placement Test (EPT) and the undergraduate program in Linguistics + TESL. I am also the faculty advisor for our student-led Language Testing Research Group. Outside the university, I am currently the president of the Midwest Association of Language Testers (MwALT).
If you are a student interested in studying language testing at Illinois, feel free to send me an email!
