Umit Tokac

Umit Tokac has a Ph.D. in Measurement and Statistics from Florida State University (FSU). He received his bachelor’s and master’s degrees in mathematics education in his home country of Turkey and a second master’s degree from FSU in Research Methods and Statistics. He worked at Center for Advancement of Learning and Assessment (CALA), FSU as a graduate research assistant on the Institute of Education Sciences (IES) project for three years. He also worked for State of Florida Department of Juvenile Justice (DJJ) as a psychometrician during graduate school. After he completed his Ph.D., he worked one year as a data analyst for Pearson Educational Testing Company and one year for Missouri Institute of Mental Health (MIMH), University of Missouri – St. Louis as an assistant research professor. His primary research interests are Bayesian data analysis applications, and adapting artificial intelligence methods to different disciplines in order to measure and monitor participants’ current conditions as well as forecast their future conditions. His area of research interest is also focused on veterans in the area of PTSD and neurological effects.
