My research has focused on developing and applying statistical genetic models to estimate population parameters, effects of single genes. Contributions include developing statistical methods to identify major genes, fine-map genomic regions affecting complex traits. I have significantly contributions are developing methods for gene mapping. My significant research success is to identify several recessive lethals in dairy cattle and significant contribution of identifying QTLs for fertility and mastitis. My research interests are as below.

• Genetic architecture for quantitative traits, understanding biology of complex traits
• Method development for genome-wide association studies (GWAS) for complex traits
• Identification of QTL for disease resistance, fertility and production traits in cattle and pigs
• Whole genome sequence variant analysis
