Professor Chang came to Purdue in August 2018. Prior to joining Purdue, he worked at the University of Illinois at Urbana-Champaign (UIUC) and held professorships in educational psychology, psychology and statistics. He is a Fulbright Scholar, an elected fellow of the American Educational Research Association and editor-in-chief of Applied Psychological Measurement, and previously served as president of the Psychometric Society. Professor Chang’s research has focused primarily on improving educational assessments, specifically on issues emerged from the K-12 accountability testing. His research interests are broad, encompassing both theoretical development and applied methodologies, including computerized adaptive testing, statistically testing item bias, cognitive diagnosis, and adaptive learning. Many of his manuscripts were published in top-tier journals, ranging from very theoretical, such as Annals of Statistics, to very applied, such as Educational and Psychological Measurement. He was included on the “Incomplete List of Teachers Ranked Excellent by Their Students” for 10 consecutive years at UIUC.
