The research program in my lab focuses on developing a better understanding of the host-parasite interactions and evolution of rust fungi. Currently, Puccinia graminis, the casual agent of stem rust, is the primary focus with projects on: comparative genomes; developing a complete genetic map; identify and characterize effector (avirulence) genes; development of rapid detection methods for Ug99 related races; race evolution.
