My methodological research focuses on models for dependent data (especially high-dimensional data such as spatial and spatiotemporal data), statistical computing, and Bayesian methods. My interdisciplinary collaborations have spanned several fields, including processive motor proteins, magnetic resonance safety, MR-based cartilage assessment, environmental and occupational health, brain imaging, the spatial epidemiology of HPV-related cancers, US childhood vaccination refusal, and WASH insecurity and psychosocial wellbeing in Ivory Coast and Nigeria. I have developed many software packages for both R and Perl.
