Todd D. Little

Founding Director

Dr. Todd LittleTodd D. Little, PhD is a Professor of Educational Psychology and Leadership and the founding Director of the Institute for Measurement, Methodology, Analysis and Policy (IMMAP) at Texas Tech University. Little has worked at the Max Planck Institute for Human Development's Center for Lifespan Studies (1991-1998),Yale University's Department of Psychology (1998-2002), and the University of Kansas (2002-2013), where he founded and directed the Center for Research Methods and Data Analysis. In 2001, Little was elected to the Society for Multivariate Experimental Psychology. In 2009, he was elected President of APA's Division 5 (Evaluation, Measurement, and Statistics). Little is a Fellow in AAAS, APA and APS. In 2009, he received the W.T. Kemper award for excellence in Teaching at KU and in 2013 he received the Cohen award for distinguished contributions to teaching and mentorship from APA's Division 5.

Kwanghee Jung

Assistant Professor

Dr. Kwanghee JungKwanghee Jung (Ph.D., McGill University), Assistant Professor of Educational Psychology and Research Associate in IMMAP at Texas Tech University. He has had extensive hands-on experiences with multivariate analysis (e.g., structural equation modeling, multilevel analysis, latent growth curve modeling, time series analysis). He has also contributed to the development and applications of quantitative methods and advanced modeling methodologies (e.g., generalized structured component analysis and constrained principal component analysis) to diverse issues and topics in human development and education, mental health and disorders, and brain imaging data analysis.

Rong Chang

Post-doc Researcher

Rong Chang, PhD is the Postdoctoral Research Associate in IMMAP. She completed her Ph.D. in Educational Psychology at Texas Tech University in 2016. Her research interests center around the construct and measurement validation, latent modeling as well as the planned missing design. She is currently involved in the research projects that are about regression analyses, structural equation modeling, and missing data analysis in longitudinal studies. In addition, she is also interested in the motivation theories and educational application, and the diversity of learning and teaching environment.
