I am a quantitative and clinical psychologist whose research focuses on advancing quantitative methodology in behavioral health intervention and health disparities research. I am presently the Director of the Methods Division at the University of Washington (UW) Indigenous Wellness Research Institute and a Licensed Psychologist in the State of Washington. My areas of research include alcohol use, chronic illness, suicide prevention, and culturally informed intervention with diverse populations. A key emphasis of my program of research is increasing the accessibility of statistical approaches that can more powerfully and accurately assess behavioral health interventions and test theoretical models of health and health disparities. My recent research has focused on identifying the features of effective interventions for reducing problem alcohol use, particularly time-limited approaches appropriate for resource-limited settings. Towards that end, I am developing new approaches for meta-analysis using individual participant data that can evaluate treatment effectiveness and pathways of change with greater accuracy than either traditional meta-analysis or single-study designs.
