Current Research Focus:

Develop and establish integrated functional genomics leading to systems biology approach to dissect abiotic stress tolerance mechanisms and yield improvement traits in plants. Large scale sequencing of the most diverse soybean germplasm in the U.S. along with the generation of additional reference genomes and pan genomes for both cultivated and wild-type soybeans using new generation sequencing technologies. Discovery of genomic regions affecting yield using whole genome sequencing technologies leading to the development of functional markers for genomics-assisted breeding strategies for better plant performance and enhanced yield.  Genome sequence information and HapMap from these studies will help the U.S. soybean community to conduct genome wide analyses and identify alleles associated with agronomically important traits.
