I am an assistant professor of methods and statistics within the Department of Child Development and Education at the University of Amsterdam. My areas of expertise primarily involve structural equation modeling (SEM), multilevel modeling, nonparametric methods, and modern missing data methods. My methodological research interests include:
- psychometrics, e.g., testing measurement equivalence and detecting differential item functioning (DIF)
- resampling methods (permutation, bootstrap, Monte Carlo simulation)
- Bayesian inference
- planned missing data designs
- statistical programming
I use GitHub to maintain two R packages (semTools and simsem) and contribute to two other R packages (lavaan and blavaan), which are all devoted to SEM in R.
I frequently teach workshops about how to use these software packages, for which I host materials here, copyrighted under CC-BY-SA-4.0.
