Throughout all of my work is an interest in quantitative methods. In particular, I am interested in epidemiological statistics, probabilistic estimation methods for record linkage, growth modeling techniques, geometric interpretations of multivariate statistics, and curvilinear and nonlinear modeling.

Some of this work is basic in nature.  For example, in the area of developmental epidemiology, I am interested in applying developmental modeling techniques to epidemiological measures of effect.  Other activities are more directly applied and illustrate my interest in using advanced or complex modeling techniques in my work or my collaborations with others.  For example, my research on parenting includes interactive curvilinear models, where hypothesized curvilinear interactions are best examined via first and second order partial derivatives of the regression equation.  My interest in quantitative methods has led to my role as a statistician or methodologist on a number of projects described in my collaborations.
