Ihnwhi Heo

Quantitative Methodologist and Statistician

CV

Bio

I am a Ph.D. candidate in Quantitative Methods, Measurement, and Statistics at the University of California, Merced. I will receive my doctorate by May 2026, with a dissertation titled Advanced Methods for Implementation of Bayesian Growth Mixture Modeling, funded by the American Psychological Association (APA) and the Society of Multivariate Experimental Psychology (SMEP).

My overarching research goal is to advance flexible modeling approaches for complex data in the social and behavioral sciences. I specialize in Bayesian inference, latent variable modeling, and missing data. With these specializations, I integrate quantitative, computational, and machine learning approaches to develop, evaluate, and implement innovative statistical methods that expand their applicability across diverse research contexts. More details can be found in the Program of Research.

As of January 2026, I have published 13 peer-reviewed journal articles, including 8 as first author, in top-tier methodological and applied journals. A complete list of my refereed journal publications can be found on the Articles page. For additional details on my academic training and experience, please see my curriculum vitae.

Program of Research

My program of research is organized around three interconnected lines.

(1) Bayesian Latent Variable Modeling

I advance Bayesian methodology for latent variable models, including structural equation models, growth curve models, and mixture models. My research focuses on Bayesian estimation and model evaluation across different prior distributions, and integrates computational methods for Bayesian model averaging and Bayesian regularization.

(2) Missing Data Analysis

I examine the impact of missing data on latent variable modeling, including latent mediation models, growth curve models, and mixture models. I further develop computational, machine learning, and deep learning approaches for handling missing data within the framework of multiple imputation.

(3) Applied and Methodological Collaborations

I collaborate with researchers across disciplines to translate methodological innovations into practice, generate novel applications, and foster work at the intersection of applied and methodological research. These collaborations span applied domains involving educational, psychological, and health data, as well as methodological areas such as educational measurement, psychometrics, social network analysis, and artificial intelligence.
