Academic interests
Currently I am working with methodological development for latent variable models such as item response theory (IRT) and structural equation models. I am also involved in research on equating/linking in educational assessment and various applications in education, gerontology and psychology. In addition, I am the maintainer of the R packages kequate, which implements the kernel method of test equating, irtreliability, which enables the estimation of IRT reliability coefficients and associated confidence intervals, and lamle, which estimates high-dimensional generalized linear latent variable models.
