Current Lab Members and Research Area

Renato Carvalho, Ph.D student

Development of a hybrid nanomaterial against bacterial spot of tomato caused by copper-tolerant Xanthomonas perforans strains and understanding the mode of action of the nanomaterial on the bacterial cell using spectroscopic and microscopic approaches is one of Renato's research areas. Renato is also conducting research on the identification of novel protectants for management of whitefly transmitted viruses on tomato and watermelon in Florida. A third area of research program is characterization of novel bacterial strains using whole genome sequencing approach.

Manoj Choudhary, Ph.D student

Sustainable management of bacterial spot of tomato using antibacterial magnesium nanomaterials is a key area of Manoj's research. Research also involves understanding the potential of integration of biocontrol agents with nanomaterials to enhance effectiveness in disease management. Another objective of Manoj's studies is to Identify the host limiting factors present in Xanthomonas perforans strains associated with their pathogenicity on tomato and pepper. Machine learning for disease image classification in tomato is another project.

Dr. Fanny B. Iriarte, Plant Disease Diagnostician

Manager of the Diagnostic Cinic and works on a daily basis in identifying the cause of plant diseases (fungi, bacteria and viruses) in infected plant samples in crop production in North Florida, and communicates with farmers, extension agents, crop consultants and master gardens to share diagnsotic information. Dr. Iriarte also provides research support on projects including bacterial leaf spot of watermelon, bacterial spot of pepper, whitefly transmitted viruses on cucurbits, and trains graduate students, visiting students and interns on basic and advanced diagnostic techniques.

Susannah Da Silva, Lab Manager

Manager of the Lab, Greenhouse and Field research on bacterial, fungal and viral plant pathogens of economic relevance to Florida. Susannah conducts research on many projects including management of bacterial speck of tomato caused by Pseudomonas syringae pv. syringae using systemic acquired resistance inducers, novel protectants against whitefly transmitted viruses on tomato and watermelon, management of powdery mildew on watermelon using disease forecasting model, and conventional and organic fungicides for management of Alternaria leaf spot on carrot.

Paret Lab - Research Profile

2021

Austin N. Fife, Ph.D student

Rose rosette disease caused by Rose rosette virus vectored by the eriophyid mite Phyllocoptes fructiphilus is the topmost disease of relevance to the rose industry in the U.S. Austin's research focusses on elucidating the biology of the eriophyid mites, understanding the potential of an integrated use of a systemic acquired resistance inducer for improving plant defense system against the virus and predatory mites for reducing the mite populations.

We are plant pathologists. You may be more familiar on a day-to-day basis with medical scientists who studies human diseases or veterinary scientists who studies animal diseases; the difference in our case is that we study plant diseases! and we study bacteria, fungi and viruses that causes diseases on plants.

Graduate students, Post-Doctoral fellows and Research scientists in our lab conduct studies on identification and characterization of plant pathogens of vegetables and ornamental crops; understanding the biology of pathogens and the etiology (cause) of plant diseases; and management of plant diseases of economic relevance in the United States. Internationally, we conduct research and agricultural development activities in West Africa (Benin, Togo, Niger, Côte d'Ivoire), Ethiopia, China, Philippines and India.
