Cambridge Global Food Security

An Interdisciplinary Research Centre at the University of Cambridge


The Grant group uses genomic and functional genomic approaches, combined with advanced molecular, proteomic and microscopy techniques, and often integrated with mathematical and statistical models, to determine the basis by which bacterial pathogens survive in the environment, colonise their hosts and cause disease. The Grant group have been at the forefront of developing genomic and functional genomic approaches to study bacterial pathogens of clinical and veterinary significance, including transposon mutagenesis, Tn-Seq, TraDIS and CRISPR technologies. Additionally, the Grant group have developed Hi-C laboratory and bioinformatic pipelines for the study of complex microbiomes and for disambiguating plasmids withing bacterial populations, including tracking antimicrobial resistance genes in complex microbial communities.
