  • Genome-informed diagnostics
  • Interface among plant, animal, and human health
  • Networking diagnostics to enhance capability and increase capacity
  • Seed-borne toxigenic plant pathogens

Lab investigates emerging diseases and is currently engaged in international biosecurity projects in Europe, the Middle East, South America, and Australia. Research centers on pathogen detection and surveillance, pathogen ecology, and epidemiology for accidental and intentional introductions; interests span from preparedness and prevention to mitigation and recovery. Of particular interest is a better understanding of the intersection of plant health, public health, and food security.
