I am working as an associate professor in Pamukkale University, and I am also a member of Bogazici University Adaptive Test Lab (BounAdaptiveTestLab). I study on Item Response Theory and Computerized Adaptive Testing.
I received my B.Sc degree in Physics Education department from Balıkesir University, Türkiye, in 2009. Then I received my M.Sc & Ph.D degrees in Educational Measurement and Evaluation department from Ankara University, Türkiye, in 2012 & 2016. I am currently associated professor in Pamukkale University, Denizli, Türkiye, and a researcher of BounAdaptiveTestLab since 2021. My research area mostly includes Computerized Adaptive Testing and Item Response Theory. I am also developer of a Shiny application, catIRT tools, that aims to help researchers to conduct CAT simulations and IRT calibrations.
