My experience broadly covers the epidemiology, diversity, and management of Phytophthora phytopathogens of woody plants. My research provides information needed to make management decisions aimed at preventing the spread of these invasive pathogens in a wide array of environments: wildlands, restoration plantings, production nurseries, and native plant nurseries. Much of my focus has been on the landscape dynamics and long-term impacts of Phytophthora ramorum, causal agent of sudden oak death in Southwest Oregon. I also focus on the distribution of soilborne pathogens in nurseries and the coastal plant communities of central California.
