My research focuses primarily on gene expression associated with P. infestans infection of tomato. I am interested in the variation in expression by identical strains when confronted with hosts of varying susceptibility. In parallel to this project, I am working to develop a reliable and practical small interfering RNA protocol for use in the P.infestans system, allowing knockdown of target genes and possibly functional analysis.
