Post-Doctoral Researcher (Forest Pathology) | May 2013 – Present

University of Florida, Gainesville, Florida

Discovery and development of cultivars with resistance to laurel wilt disease.  Field and greenhouse experiments of host and vector roles in disease development.  Propagation and maintenance of plant and fungal germplasm.

 

Current Projects

  • Selection and vegetative propagation of survivor redbay (Persea borbonia) trees from areas heavily affected by laurel wilt.
  • Screening redbay germplasm for tolerance to the laurel wilt fungus (Raffaela lauricola) via artificial inoculation experiments
  • Development of redbay cultivars tolerant to laurel wilt for restoration plantings
  • Explore the effects of laurel wilt infection upon host plants volatiles and its effects upon the host seeking behavior of the redbay ambrosia beetle (Xyleborus glabratus)
  • Determine the genetic diversity of R. lauricola within the United States
