Dr. Choi Ji Yeh joined our department in July 2017. She received her Ph.D. in quantitative psychology at McGill University, Canada. She is interested in addressing diverse issues and topics in psychology and other social sciences by developing and applying statistical and computational methods. Particular research interests lie in areas of structural equation modeling, functional data analysis, multivariate statistics, high-dimensional data analysis, cluster analysis, and Bayesian statistics.
Her current focuses are on 1) developing a statistical method that integrates the component-based structural equation modeling into a Bayesian framework, 2) extending data reduction techniques for functional data, where observations are measured continuously over a large number of occasions, and 3) understanding and capturing cluster-level respondent heterogeneity inherent to data.
