• Development of Bayesian method for multi-trait whole-genome analyses that combines information from genotyped and non-genotyped individuals.
• Developed a single-site Gibbs sampler for variable selection on trait-specific marker effect.

• Developed a QTL model for whole-genome analyses that fits allelic effects for unobserved quantitative trait locus genotypes rather than the effects for observed markers; applied this methodology to genomic prediction.
• Developed a nested model, BayesN, that accounts for structures in genome and speeds up the analysis of high-density SNP or sequence data; applied this methodology to bovine 50k and 770k SNP chips and 1000 Human Genome.
• Proposed a procedure for controlling posterior type I error rate or proportion of false positives (PFP) in genome-wide association studies.
• Developed a dominance model for whole-genome analyses that incorporates the additive and dominance effects of SNP markers with dependent or independent mixture priors.
• Aided collaborators to apply the dominance model that I developed in purebred selection for crossbred performance and genetic dissection for complex traits, including disease resistance in animals and plants; Generated.
• Developed a C++ program where all these methods that I developed and most of the commonly used methods for whole-genome analyses were implemented as objects.
