The majority of my time involves the coordination of our lab’s ornamental and ginseng research trials in Michigan and Wisconsin.  This research includes the testing of newly registered and experimental fungicides against various fungal pathogens.  I also coordinate the lab’s GLP residue trials on vegetable and specialty crops.  My master’s research is epidemiology and management of coleus downy mildew, caused by caused by Peronospora sp., a new pathogen of coleus.
