The focus of my breeding program as the Robert A. Nilan Endowed Chair in Barley Research and Education is the development of high-quality spring and winter malting, food and feed barley varieties that are widely adapted to diverse regions of Washington State. As part of these efforts, I founded and serve as the director of the WSU malt quality analysis lab to analyze material from my breeding program as well as to serve the craft malting, brewing and distilling industries with third party analysis. My basic research utilizes molecular genetics, genomics, and functional analysis tools to explore the genetic and functional mechanisms underlying biotic and abiotic stress resistance and malt quality genes in barley. The genes and signaling pathways my team is focusing on are important to production in the growing regions of Washington State and the greater inland northwest. The knowledge and molecular tools developed can be translated to the field through targeted breeding efforts aided by genetic marker-based and genomic selection strategies.
