Area(s) of Expertise

My research interests cover applied and molecular plant pathology, and genomics with a major emphasis on bacterial and fungal population biology of tomato and strawberry pathogens; integrated disease management; plant microbiome; plant-pathogen interactions; disease resistance genes/QTLs discovery through linkage mapping and genome-wide association study (GWAS), and next-generation sequencing (e. g., RNA-sequencing, and genotyping-by-sequencing).
