Akihito Kamata, BRT Affiliate
Dr. Kamata is the Executive Director at the Center on Research and Evaluation (CORE). He has also been a Professor at Southern Methodist University since August 2013 (Department of Education Policy & Leadership, Center on Research and Evaluation, Simmons School of Education & Human Development; Department of Psychology, Dedman College of Humanities and Sciences). Prior to joining SMU, Dr. Kamata was a faculty member at the University of Oregon and Florida State University.
Dr. Kamata's primary research interest is psychometrics and educational and psychological measurement, focusing on implementation of item-level test data analysis methodology through various modeling framework, including item response theory, multilevel modeling, and structural equation modeling. He did pioneering work on multilevel item response theory modeling, where item response data from individuals are nested within group units, such as schools. This line of work is represented by his 2001 publication in Journal of Educational Measurement, a special issue on multilevel measurement modeling in Journal of Applied Measurement in 2005, and several book chapters on the topic, including a recent chapter in the Handbook of Advanced Multilevel Analysis (2011). Other recent interests include developing effect size measures for testlet modeling, developing reliability measures of growth trajectory for longitudinal data modeling, and Bayesian inference for complex psychometric models.
Dr. Kamata received his doctoral degree in Measurement and Quantitative Methods from Michigan State University in 1998.
