Available: 08/17/17, Expires: 08/13/18

Clinical diagnostic laboratory tests for the basis of a majority of medical decisions, yet are not ready for the new era in precision medicine. Specifically, health care administrators use reference intervals -- the range of a diagnostic that deems an individual "healthy" or sick -- that are "one size fits all" and based on a few people in the US population. In this project, we will use data science and bioinformatics to mine for optimal reference ranges for population subgroups, such as race/ancestry, sex, and age. The project will entail building analyses to compute risk for health outcomes based on subgroup-specifics reference ranges. The student will get hands-on experience in bioinformatics, clinical diagnostics and phenomics, genomics, data mining and statistics.
