My current research is organized around two lines of inquiry: 1) Identifying which aspects of the built and social environment matter most in helping older adults maintain independence and physical mobility, and; 2) Examining life course sociobiologic mechanisms (e.g., viral infections, mitochondrial function) that drive disparate outcomes in physical disability especially related to neighborhoods.
