I’m currently an Associate Professor of Foreign and Second Language Education at Florida State University where I teach undergraduate and postgraduate courses in second language acquisition and language pedagogy. Prior to my appointment at Florida State University, I was a  Senior Lecturer of Applied Language Studies at the University of Auckland, New Zealand. I have taught ESL at several U.S. and Chinese universities and beginning Chinese classes at two U.S. universities. I received my Ph.D. in Second Language Studies from Michigan State University.

My research interests include language aptitude, working memory, form-focused instruction, task-based language teaching, corrective feedback, and research methods. My primary interest is in investigating how the process and product of second language learning are  affected jointly by instruction and learners’ cognitive and affective differences.  My ultimate goal is to reveal how learner-external and learner-internal factors interact to influence learning success and explore ways to cater to learners’ individual differences such as by identifying instruction types that fit different types of learners and designing tasks that minimize the unfavorable effects of individual difference factors.

In addition to a number of large-scale primary studies, I have conducted several meta-analyses aggregating the quantitative results of the research on the effectiveness of instructional treatments and the predictive power of cognitive aptitudes. The meta-analyses, which are based on the totality of the research on the investigated topics, have  allowed me to provide unequivocal answers to questions theorists, researchers, and practitioners have about the relevant constructs. They have also enabled me to identify the strengths and limitations of existing research and recommend ways to advance the research in the related substantive domains.
