Extension and Research Interests:  
  My extension program consists of managing the Florida Extension Plant Diagnostic Clinic at NFREC, Quincy, providing leadership and coordination for north Florida county faculty and producers on the etiology and management of horticultural crop diseases, and developing UF/IFAS Distance Diagnostic and Identification System (DDIS) concerning plant diseases in Florida. 
    My research activities mainly involve diseases of vegetables and woody ornamental crops which are important in North Florida. I focus on the etiology, biology and epidemiology of these diseases, as well as genetic diversity of bacterial pathogens. Interdisciplinary approaches for disease management by reduced-risk compounds, cultural practices and host resistance are important aspects of my research program (http://plantdoctor.ifas.ufl.edu).
