I am interested in all phases of research methodology and quantitative analysis as they apply to evaluation research. I am particularly interested in health outcomes for individuals with disabilities. I am a member of the Evaluation Group for Analysis of Data (EGAD) and PERM (the Program Evaluation and Research Methodology group). I also serve as the editor of the Journal of Methods and Measurement in the Social Sciences. https://journals.uair.arizona.edu/index.php/jmmss/index
