Research interests:
My current methodological work focuses on exploring the finite-sample properties of popular methods used to estimate SEMs and GLMMs, with emphases on assessment of model fit, parameter estimate bias, and coverage.  In the area of structural equation modeling, I am developing modifications to popular estimation methods that are robust with 'small' samples, and simultaneously support defensible modeling of nonnormally distributed data with missing values.
