Dr. Jung Yeon (Ellie) Park is an Assistant Professor of Quantitative Research Methods at GMU (Spring 2020 - Current). She received her PhD degree in Measurement, Evaluation, and Statistics from Teachers College, Columbia University (2015) and M.S. in Statistics from The George Washington University (2009). Prior to joining Mason, Dr. Park was a senior statistician at ITEC - KU Leuven's Smart Education Program for projects to advance adaptive e-learning assessment and learning analytics methods to support technology-enhanced learning (2017-2019); and a postdoctoral associate for projects identifying risk and protective factors for suicides among sexual minority youth at New York University's Institute of Human Development and Social Change (2016). She served as a program chair for European Conference on Artificial Intelligence (ECAI; 2020) and a proposal review panel at NSF (2021, 2022).       

She teaches doctoral-level quantitative methods courses including: Bayesian Methods (EDRS 897), Quantitative Methods in Educational Research (EDRS 811), Advanced Applications of Quantitative Methods (EDRS 821). 

Research Interests

Dr. Park's research focuses on Psychometric Modeling and Statistical Inference to understand marginalized populations in the fields of Education, Mental Health, and Applied Psychology. Her work was published in peer-reviewed journals such as Large-Scale Assessment in Education, Developmental PsychologyJournal of Applied Statistics, Behavior Research Methods, and Computers & Education

Dr. Park's research interests include Latent Variable Modeling (Cognitive Diagnosis Models, Item Response Theory Models), Bayesian Data Analysis, Learning Analytics (Adaptive Learning System), and Longitudinal Data Analysis. 

She is a program evaluator of DOE's NPD Grant titled "Advancing Content-Integrated Education for English Learners with a STEM-focus (ACE-STEM)".
