My name is Jung Yeon (Ellie) Park. I am an Assistant Professor (tenure-track) of Quantitative Research Methods in the Division of Educational Psychology & Research Methods, CEHD. 


  • PhD, Measurement, Evaluation, & Statistics, Columbia University, New York, NY 
  • MS, Statistics, George Washington University, Washington, DC

Postdoctoral Training

  • itec, imec research group, University of Leuven (KU Leuven), Belgium (2017-2019)
  • Institute of Human Development and Social Change, New York University, New York, NY (2016)
Research Interests

My research interests include:

  • Latent variable modeling (e.g., cognitive diagnosis model; item response theory) 
  • Longitudinal data analysis
  • Bayesian data analysis 
  • Learning analytics (e.g., adaptive learning systems)
