Biosketch

I am an Assistant Professor in the Department of Measurement, Statistics, and Evaluation at the University of Maryland. I joined the faculty of EDMS in Fall 2007 after working as a psychometrician on k-12 state assessment programs for about four years. Before working full time in psychometrics, I studied at the Florida State University for my doctoral degree in Measurement, Statistics, and Evaluation. Prior to the graduate studies in the United States, I taught ESL in the College of Foreign Languages at Shanghai Jiao Tong University in China, where I completed my M.A in Linguistics and Applied Linguistics and my B.S. in English for Science and Technology.

I have taught EDMS 645-Quantitative Research Methods I covering topics on basic descriptive and inferential statistics and EDMS 646-Quantitative Research Methods II constituting advanced topics in the analysis of variance (ANOVA). I am currently teaching a seminar-based course on psychometrics in large-scale assessments which includes topics on test assembly, calibration, equating, vertical scaling, dimensionality, local item dependence, differential item functioning, and computer-based testing.

My research interests include item response theory, multilevel measurement modeling, finite mixture modeling, and their applications in solving psychometric issues in large-scale educational assessments. I am currently exploring combining these modeling approaches to deal with complicated data analysis in large-scale assessment settings. In addition, I am also interested in using computer-based tests for classification deicisions.
