Song develops statistical methods of homogeneity pursuit in regression analysis, including statistical theory, integer optimization, and algorithms to help practitioners to understand the influence of environmental mixtures in health outcomes.
Song develops optimal algorithms to create optimal organ matching strategies in the kidney paired donation program to increase the quantity and quality of organ donation in kidney transplantation.
Song develops statistical methods and algorithms to discover high-dimensional causal mediation pathways of omics biomarkers that enable scientists to evaluate and validate how social and environmental determinants affect human growth and development.
Song develops statistical methods, distributed inference, algorithms and software in big data integration and computation.
