Dr. Kamata is a Professor at Southern Methodist University (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 in 2013, Dr. Kamata was a Professor 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. Currently, Dr. Kamata's primary focus is on psychometric model development for oral reading fluency (ORF) assessment data, through three grant projects funded by IES: U.S. Department of Education. Previously, Dr. Kamata 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).
Dr. Kamata received his doctoral degree in Measurement and Quantitative Methods from Michigan State University in 1998.
