💡 Cheng Lab at UC Davis



Our research interests are broadly involved in the development of statistical and computational methods for the (genetic) improvement of populations through more accurate, efficient, and biologically meaningful analysis. We have focused on the use of phenomics, genomics, pedigree, and other sources of big data in various species to better predict desired traits. These endeavours include
