Area of Specialization

Diseases of vegetable and field crops, mushroom production.

Research

Research interests include the epidemiology and control of diseases of vegetables and field crops of northern and central California, especially those caused by fungal and bacterial pathogens; interactions between fungal pathogens and mycorrhizal fungi; and cultivation and phylogenetics of mushrooms.
