Genetic Epidemiology Projects
Our research program focuses on racially diverse populations which have varying ancestral population contributions. For example, African Americans have proportions of African and European ancestry. We leverage this genetic diversity and apply it to epidemiologic studies of disease, such as improved predicted lung function equations (Kumar, Seibold, Aldrich et al. 2010). Most genetic studies have been conducted in populations of European descent. Understanding genetics of diverse populations presents an opportunity for improved precision medicine. We have ongoing genetics projects within the Southern Community Cohort Study, the Vanderbilt Thoracic Oncology Biorepository, and the Vanderbilt DNA biobank. New collaborative projects are exploring the pulmonary microbiome.

Our team has expertise in various forms of “big data”, ranging from genome-wide association studies to geospatial examination of clinical practice across the United States.
