Professional Summary

Dr. Youn Seon Lim is Assistant Professor of Quantitative and Mixed Methods Research Methodologies (QMRM) at the University of Cincinnati.  Youn Seon teaches courses in introductory and advanced statistics and psychometrics.  Her research concerns multivariate latent variable modeling, including Nonparametric and Bayesian approaches, in educational and psychological measurement and survey research.  Youn Seon has published on algorithms for estimating the Q-matrix of cognitively diagnostic assessments, on Bayesian estimation routines for large multidimensional diagnostic classification models, on model-fit statistics, and on fitting nonparametric hierarchical diagnostic classificaiton models to nested response patterns.  

Prior to joining the faculty at QMRM at the University of Cincinnati, Youn Seon was Assistant Professor of Data Science and Biostatistics at the Donald and Barbara Zucker School of Medicine at Hofstra University/Northwell in Hempstead, NY.  Youn Seon did post docs in Prof. Fritz Drasgow’s Psychometric Laboratory at the University of Illinois, Urbana-Champaign and at BIFIE in Salzburg, Austria. (BIFIE stands for "Bundesinstitut für Bildungsforschung, Innovation & Entwicklung des österreichischen Schulwesens" [Federal Agency for Educational Research, Innovation, and Development of the Austrian Schooling System]—BIFIE is kind of the Austrian equivalent to ETS.)
