I am an assistant professor in the Department of Instruction and Learning and a research scientist at the Learning Research & Development Center (LRDC). I graduated with a Ph.D. in Curriculum and Instruction with an emphasis on reading education from the University of Maryland, College Park. Previously, I was a teacher of language and literature at secondary schools in Seoul, Korea, and later worked as an assistant professor at Iowa State University. I identify myself as a literacy researcher who seeks theoretical background mainly from perspectives in reading comprehension, situated learning, and digital literacies. Of particular interest to me is examining the nature of cognitive, metacognitive, and epistemic processes that readers engage in during meaning making in diverse multisource text environments and, thereby, finding ways to inform practice in the teaching and assessment of reading competence as a configuration of the range of sophisticated knowledge and skills. Currently, I am co-leading various research projects, such as middle school learners' historical practices in disciplinary multisource comprehension instruction, evidence-centered assessment design for core literacy skills in digital settings, and bilingual learners' translanguaging in online reading. I present my work regularly at national/international conferences including American Educational Research Association and Literacy Research Association. My publications have appeared in several peer-reviewed journals such as Cognition and Instruction, Reading Research Quarterly, Theory Into Practice, Journal of Adolescent and Adult Literacy, and Korean Language Education Research. Informed by research, my teaching centers on theoretical perspectives as well as pedagogical practices in reading and literacy. Here at Pitt, I teach IL 3015 Theoretical Perspectives in Language, Literacy, & Culture II for doctoral students in LLC and IL 2219 Disciplinary Literacy for masters students.
