About the Presenter

Duke Pauli is a graduate student at Montana State University. His work primarily focuses on the development of new malting barley varieties for the Montana production region using genome-wide association mapping to identify novel beneficial alleles that can be incorporated into barley breeding programs. His work also focuses on the implementation of genomic selection and understanding the utility of genomic selection on regional plant breeding programs.
