What I do
I work for the Center for Statistical Consultation and Research, as the primary SAS consultant. I also teach a course in Statistical Computing Packages (Biostat 510) in the department of Biostatistics each fall term. I present workshops on Introduction to SAS and Intermediate SAS each semester, and am a co-presenter for a workshop on Generalized Linear Models and a workshop on Introduction to Proc Mixed for correlated and longitudinal data in the spring.

I am interested in models for correlated data for continuous outcomes, and generalized estimating equations and other models for correlated discrete outcomes.
