Areas of Specialization/Research
  1. Development and integration of economical and sustainable strategies for plant disease management and food safety practices in vegetables and other horticultural crops. 
  2. Development of effective communication and information exchange strategies, specific to horticultural producers in Louisiana and surrounding states, through the use of mental models, operation risk assessments, expert elicitations and scoping or systematic reviews.
Current Research and Extension Outreach Activities
  1. Operational risk assessment and expert elicitation of risk factors for microbial contamination in the tomato greenhouse production chain.
  2. Development of co-management sanitation practices to mitigate the risk of Xanthomonas gardneri, Clavibacter michiganensis subsp. michiganensis and Salmonella spp. in pelleted tomato seed.
  3. Development of an interactive best management practices guide for vegetable transplant production.
