The primary focus of my research is to understand how social and environmental conditions impact the health of older adults. For example, in recent projects I have identified neighborhood design features associated with increased walking among older adults, demonstrated that improving neighborhood accessibility slows functional decline among older women, and uncovered racial/ethnic differences in health behavior change after diagnosis with chronic illness. My current research employs analytic methods used in 'big data' to examine how socioenvironmental determinants interact to hasten or delay functional decline. Ultimately, my goal as a researcher is to inform community-based programs and policies that support healthy aging, prevent or delay functional decline, and reduce health disparities among older adults. In addition to gerontological research, I am currently co-investigator on a national-level effort to reduce the burden of diarrheal and respiratory disease in Rwanda by providing point of use water filters and improved cookstoves to roughly two million households. Methodologically, my areas of interest include multilevel and latent growth modeling, complex survey analysis, causal inference, machine learning, and missing data handling. My teaching activities are primarily focused on the Oregon Masters of Public Health program, and I hold a joint appointment in the OHSU School of Medicine, Division of Epidemiology.
