Genomic data can be used to try to explain complex phenotypes, ranging from diabetes to crop yield. The success is frustratingly inadequate in some respects and spectacularly successful in others. Broadly speaking, only a small proportion of the loci that affect such traits can be identified, even in large studies; conversely, simple whole-genome regression can predict the trait (disease susceptibility, crop yield etc) with remarkable efficiency. The student will combine the gene-hunting (GWAS) and regression (Genomic Prediction) approaches in a Bayesian framework to improve both the identification of key loci and the accuracy of the predictions.
