Statistical Genetics
The methodological approaches of genetic epidemiology and statistical genetics are primarily focused on the identification of genetic variation underlying complex disease. Here at IBG, there is a particular interest in the genetics of psychiatric, behavioral and neurologic disorders. IBG researchers make use of well-characterized longitudinal data arising from both family-based and population-based samples. Statistical and epidemiological approaches being used at IBG include genome-wide array and sequence-based association, polygenic scores, Genomic SEM, and SNP-based heritability.

All human studies utilize statistical genetics. IBG uses data from the following studies, and others:
