Areas of Interest
Wheat and Barley Molecular Genetics
Research
My position is focused on wheat and barley molecular genetics. One area of my research is directed towards Fusarium head blight (FHB) of wheat and barley. Another research area is focused on developing and integrating genomics resources into barley breeding programs. Other areas involve identifying genetic variation in wild barleys for use in germplasm enhancement, and to genetically characterize a collection of barley tillering mutants.
