Other Teaching and Advising

As an advisor, I strive to foster independence and personal responsibility, and promote strategic thinking, knowledge synthesis and communication skills. The goal is to empower postdoctoral associates, graduate students, and summer interns, and prepare them for a productive life in a global society.

Program Focus

The overall goal of my research is to develop science-based sustainable solutions to plant biosecurity, water and environmental sustainability in a changing climate. This is accomplished by developing a better understanding of pathogen aquatic biology and microbial ecology in runoff water containment basins and converting agricultural wastes to invaluable resources.

Current Projects

  • “Integrated management of zoosporic pathogens and irrigation water quality for a sustainable green industry” – this project funded by USDA-National Institute of Food and Agriculture (NIFA) – Specialty Crop Research Initiative (SCRI) is a joint effort with seven institutions and in partnership with the ornamental horticulture industry across the nation. This project focuses on development of protocols to help farmers capture and reuse runoff water for irrigation without recycling and spreading plant pathogens by better system designs (www.irrigation-pathogens.info).
  • “Oomyceticide resistance and Phytophthora disease management for a sustainable ornamental horticulture industry” – this project supported by USDA-NIFA Southern Region IPM Special Grants Program is a joint effort with colleagues in several institutions of Southeastern States (GA, NC, SC, TN, TX).  This regional project assesses the status of Phytophthora resistance to mefenoxam and phosphite in the ornamental horticulture industry and develops strategies for risk mitigation.
  • “Detection of Phytophthora ramorum in the waterways of Virginia” – this project sponsored by USDA Forest Service via Virginia Department of Forestry focuses on risk mitigation of this high-impact pathogen.   
  • “Soil biology of the boxwood blight pathogen Calonectria pseudonaviculata” – this project supported by VA Agricultural Experiment Station focuses on development of practical solutions to this emerging disease.
  • “Aetiology of emerging ornamental crop diseases” – this project supported by VA Agricultural Experiment Station addresses the emerging needs of the horticulture industry for disease control solutions.

Program Focus

The primary goal of my extension program is to empower clientele to make informed management decisions on crop health, water shortage and agricultural runoff, three highly interconnected issues of global significance. I also conduct a variety of programs to meet their routine and emerging needs for disease control.

Current Projects

  • Development of an online knowledge center for irrigation pathogens and water quality
  • Diagnostics of plant disease samples to help formulate disease management programs
  • Fungicide trials to provide immediate and practical solutions to major disease problems.
