Research

Broadly, my main research interests are in categorical data analysis, latent variable modeling, and research methods. I like to use these methodologies to answer pressing research questions in the field of educational research.
Specifically, my current research interests are:

    Exploratory Data Analysis for Categorical Data
    Measurement Invariance
    Modeling Zero-Inflated Count Data

    Item Response Theory
    Latent Variable Modeling
