I currently work as an Assistant Professor and Director of the Statistics and Information Center (CSI) at Prince Sultan University. I have worked as a consultant and psychometrician at the National Centre for Assessment (NCA, Qiyas) since April 2017. I received my Ph.D. degree from Hacettepe University, Ankara, Department of Educational Measurement and Evaluation in 2015. My dissertation topic focused on examining the effects of different item-level dimensionality models on multidimensional computerized adaptive testing (MCAT) methods. My specific research interests include adaptive, language testing, multistage adaptive testing, item response theory (IRT) models, multilevel modeling, multivariate statistics, test equating, and differential item functioning (DIF).
