Philippe Rast, Ph.D.
Professor
I work in the development, evaluation, and application of quantitative methods, mainly longitudinal models for examining change over time and how individuals differ in these changes. I integrate methods for simultaneously examining intra-individual variability (change at the individual level) and inter-individual differences in such changes. My interest is generally on linear and non-linear longitudinal models that include submodels for modeling within-subject variance.
