Bio

I am currently an associate professor at the University of Maryland (UMD), College Park specializing in educational measurement and psychometrics in large-scale assessment. I received my doctoral degree from Florida State University. Prior to joining the faculty in Measurement, Statistics, and Evaluation at UMD, I worked as a psychometrician at Harcourt Assessment on different state assessment programs for over four years.

The overarching goal of my methodological research is to improve the practice in educational and psychological assessment and develop solutions to emerging psychometric challenges. Many of these are due to the use of more complex innovative assessment formats. I believe that ultimately this work will promote the use of assessment data for cognitive diagnosis to facilitate learning and instruction. I have successfully established a coherent program of research by integrating item response theory (IRT) models, cognitive diagnostic models (CDM), and machine learning methods with multilevel and finite mixture modeling approaches with an aim to exert a positive and lasting effect on measurement practice in large-scale assessments and for cognitive diagnosis purposes.

My research agenda can be summarized into five general categories: methodological research on local dependence due to the use of testlets, modeling and methods for classification and cognitive diagnosis, Bayesian model parameter estimation, research on computer-based testing, and practical psychometric issues in large-scale tests. My methodological research has been recognized by a national award, academic work including numerous edited books, book chapters, refereed journal papers, and national and international invited and refereed presentations and over $4 million research grants and contracts on which I serve as PI or CO-PI. I proposed a multilevel testlet model for mixed-format tests that won the 2014 Bradley Hanson Award for Contributions to Educational Measurement by the National Council on Measurement in Education.

I have participated in a variety of professional service activities. I am currently chairing the Technical Advisory Committee (TAC) for the Maryland state testing programs, working with the TAC members to help the state provide rigorous testing programs. As Director of the Maryland Assessment Research Center (MARC), I work with the team to provide psychometric research and service to meet the State assessment needs. I have also served on the Research and Psychometric committee for the PARCC consortium testing program representing Maryland and currently on the Research Advisory Committee for the Prince George Public School of Maryland . Further, my research expertise has been recognized by being voted Chair Elect for the Rasch Special Interest Group for the AERA, Co-Chair and Chair of the AERA Division D2 program, Co-Chair and Chair of the AERA Division D Significant Contribution to Educational Measurement and Research Methodology Award Committee and serving on the Early Career Award committee. As a co-chair, I am working with a team to host the 2021 International Meeting of the Psychometric Society (IMPS) on the UMD campus.

I have been invited to serve on the editorial board for the American Educational Research Journal - Teaching, Learning, and Human Development section, and am presently on the editorial boards for several journals: Educational Measurement: Issues and Practices, Measurement: Interdisciplinary Research and Perspectives, Educational Assessment, and the Methods in Psychology journals. I am also on the Editorial Board of the Springer book series: Methodology of Educational Measurement and Assessment. In addition, I served as a reviewer for national conferences, journals, and books on large-scale assessments. I also served on review panels for the Discovery Research PreK-12 (DRK-12) program for National Science Foundation and grant proposal reviewer for the Methodology, Measurement, and Statistics program the National Science Foundation. I am currently serving as guest editor for two special topics on “Process Data in Educational and Psychological Measurement” and “Cognitive Diagnostic Assessment for Learning” in Frontiers in Psychology. I co-organized several MARC annual conferences and co-edited the books on different cutting-edge topics in assessment including technology-enhanced innovative assessment, the applications of artificial intelligence in assessment, and enhancing effective instruction and learning using assessment data: theory and practice.
