My research focusses on the development and application of advanced statistical techniques for the evaluation and interpretation of longitudinal data, from simple pre-posttest designs to complex and intensive longitudinal data designs (e.g. momentary assessment). I am specifically interested in structural equation modeling techniques (e.g. factor analysis) and possible violations of measurement invariance (e.g. measurement bias or differential item functioning), but my interests also include more general psychometric topics (e.g. how to operationalise and interpret different types of change).
