Plant-microbe interactions, improving food security and plant health.
Dr. Harrison leads a multidisciplinary research group that seeks to understand the evolutionary process that occur between pathogens and plants, specifically the evolution of host resistance and pathogen virulence and in the case of strawberry, the role that polyploidy plays in these interactions. His group studies the genomic architecture of bacteria, fungi and oomycetes at the molecular and the population level. The group works with genetically complex crops such as strawberry, apple and broadleaf tree species and work in these crop systems is directed towards identifying the molecular mechanisms controlling resistance to a range of plant pathogens.
Many of the current research projects that he leads have a translational component that aims to utilise information about the pathogen’s effector gene complement to enable plant breeders to select and pyramid resistance. To carry out translational genomics work in non-model crops, part of the group develop bioinformatics tools for the analysis of complex, highly heterozygous genomes. All research sits within the broad area of improving food security and plant health.
