Analysis of pathogen and disease management of trees and woody shrubs enables us to learn what causes plant diseases, how they develop and how we can manage them. Through this research, we explore the epidemiology, taxonomy, and biology of woody plant diseases.



Current Research

  • Disease Management Product Efficacy
    We research disease management options, application methods, and timing that can counter new pathogens, unpredictable weather, and perceptions surrounding pest control activities.
  • Cultural Practices for Plant Resilience
    We research cultural practices that improve plant health and reduce disease severity and incidence among trees in the urban landscapes, which are often poorly planted and maintained. We study soil health, suppressive soils, and the influence of pruning on disease.
  • Biology and Epidemiology of Woody Plant Diseases
    We investigate how diseases work and spread by studying their progression and pathogen biology. Using these insights, we explore novel and targeted management tactics.
  • Taxonomy, Biology, and Systematics of Wood Decay Fungi
    We examine wood decay fungi that infect living trees reducing the structural integrity of wood and increasing the likelihood of failure of trees or tree parts. We characterize wood decay rates and severity, which vary among these species.
